I've been pulling moulding and trim off and on for a few days for an upcoming custom closet install. The community was great in helping me to figure out ways to get the trim off the wall. I've discovered some oddities with the subfloor and wanted your opinions.
Is it normal for these types of gaps and holes to appear on the subfloor of a hardwood floor? The closet is on the second floor but there seems to be considerable gaps between the drywall and edges of the plywood. The wall that this sits on is an exterior garage wall. I'm concerned that this is a sign of a problem with the subfloor that should be fixed. Are these holes and gaps anything to worry about, aside from vermin and pests? Can I seal them with expanding foam, do I need a flooring contractor to come fix this, or is this relatively normal?
Thanks again for your help.

Vermin would be my only concern. Spray foam is not the best sealer for the critters but staple some steel wool over the opening and put the spray foam on that.
The foam encapsulates the steel wool using less foam and critters don’t like chewing on the steel wool (they will tunnel through spray foam very quickly).
Those gaps look larger than I like but as long as your trim covers the edges there is nothing to worry about, possibly a rodent highway under the trim if not filled but no structural issues.
