I need a wiring diagram to help with the re-wiring of a bedroom and bathroom. I will use 14/2 and 14/3 for all lights, then 12/2 and 12/3 for all outlets, ALL LIGHTS will be LED. The whole home will eventually be controlled by a smart system such as lutron radiora2 so I will be using smart switches etc. Bedroom will have a ceiling fan with light combo on a 3 way switch with speed control and dimmer, I was thinking I would run power source 14/2 wire from main lug to switch A then run 2 pieces of 14/3 wire from switch A to Switch C which would be the end of the switch loop and from switch C then run a single 14/3 to the ceiling fan / light combo. But from this point I need to get power to switch B and D which are for two separate closets which will have an LED light strip inside closet above door but I want the switch to control power to the light in each closet independently thus meaning that the ceiling fan light being on or off does not affect turning on or off the closet light. Question is what is the best way to wire this scenario.
Also
I would like to rewire the bathroom with a 2 gang box that would control a ceiling light with built in exhaust fan in center of bathroom, a recessed can light in shower stall, and a vanity light above sink. I was thinking one switch would control the shower light and exhaust fan seperately via a lutron one gang double switch then use the second gang to control the center ceiling light and vanity light both also independent via another lutron single gang double switc, thus having two switches controlling 3 separate lights and a exhaust fan all independently. I also need to have a double gang GFCI near the sink for my wife and her hair dryer etc. I actually have two bathrooms that are fairly close to each other and I am not sure if I can use one power source to feed the GFCI outlets used in both bathrooms or if each bathroom needs to be independent also not sure if I can run one 14/2 power source to control just the lights in both bathrooms since each bathroom is the same setup and the light will also be LED so not much of a draw. As per code does all wiring for bathrooms need to be completely independent or can a bathroom share power from another bathroom. What would be the best way to wire this bathroom as shown in drawing attached.
Any and all help or drawings you could provide would be greatly appreciated. Thank you all in advance. I have attached drawings with notes for your information.

Bathrooms
Bathroom fixed loads like lighting and fan can be served by any convenient circuit.
With the bathroom receptacles, you have two choices.
You can go either way.
Switched receptacles
When having split receptacles (one unswitched, one switched)... the usual way that will be most understandable by "the next guy", and keep box fill sane, is to do switched receptacles is off the same circuit that powers the unswitched receptacles. So in that case, you connect 12/3 between the two split receptacles, and from one split receptacle to the switch. Remember, you need to carry /3 to a switch loop because you must bring neutral in a switch loop. You cannot use neutral from the other circuit!!!
Because you will have two different circuits in the same box, you must be very careful not to mix them. You might even consider putting this switch in a different junction box, to remove all risk of confusion.
Having made the /3 connections between the two receptacles and the switch, you now can supply power in any of these locations - or really, anywhere else in the circuit. Since I would be worried quite a lot about box fill in switch #1, I would consider feeding power into the receptacle circuit at the near receptacle.
Off the far receptacle (or anywhere in the circuit), you then continue with 12/2 cable carrying always-hot and neutral to other outlets.
The second way to do it is to put these switched sockets on the lighting circuit. In that case, the switch box would be all one circuit and that would ease box fill there. But now you are running two complete circuits to the switched/split receptacles, although you can use /2 cable. You will need to break off both the hot and neutral tabs and take care to keep separation of circuits. Which will make box fill worse at the receptacles.
Closet lamp #4
Given the proximity of closet lamp #4 to a receptacle location, consider powering closet lamp #4 off the receptacle circuit instead of the lighting circuit. This will need #12 wire because ALL wiring in a 20A circuit must be #12, no exceptions. It is totally legal to do this, it's just not recommended to put lighting on receptacle circuits generally, because if you overload a socket, the breaker trip will plunge you into darkness. That's not a big issue on a single closet.
By the way, no receptacles allowed in closets, and lamps can't be where clothing can touch them.
Box fill
Switches 1 and 3 are going to have a rather significant box-fill problem. I believe we discussed this six months ago on the three-fan circuit. Be careful selecting your boxes so they are large enough, I'm fond of 4-11/16 square steel boxes and either 1-gang or 2-gang mud rings.
