Francis, that's a lot of questions and I'm not really sure what you're asking. My opinion is already posted here. I really wouldn't worry about current roster cuts and the transfer portal for a school you may or may not even have communication with.
I have a 2022 who is talking to a bunch of schools from P5 to average D1s. If he doesn't get an offer from a school he would want to go to after Ft. Myers, he'll bet on himself, shut it down and get better for the following summer. He's not going to talk to schools all winter and spring in an effort to get an offer when nothing new is happening.
Finish the fall, see what happens. If there's nothing new you either take what's there or you hold out and get better. There is no guarantee that what's already there will still be there in July. Schools want to be loved too.
