I think most conservative Bible-believing Churches would certainly accept any former trans, homo, or lesbian who spoke out against the LGBTQP movement. My Methodist congregation is very conservative, but it does not put on any airs of being self-righteous.
Liberal churches on the other hand would try to tell the repentant that they had no reason to repent. That would be very depressing indeed.
I’ve seen the opposite. Few churches accept them despite repentance. You’re is a good church.
