Just the field of physics is so large that most would probably not dare to state criticism in other sub fields. Like a Nobel prize winner in solid state physics would never judge the work of a high energy particle physicist and vice versa.
Hossenfelder is definitely qualified to talk about the OP, but her videos about transgender people shouldn't be given more credit than videos from almost any other person.
There is definitely value in people popularizing scientific consensus even when they aren't experts in the field, Bill Nye talking about climate change is useful even though he's not an expert. But when you aren't an expert and aren't trying to convey the consensus of people who are experts, you're Just Some Person With An Opinion.
