Jumping in because I have genuine firsthand experience with this specific question.
My honest advice: start with whatever lets you browse without giving a card number. That single filter cuts out most of the less trustworthy options.
The mainstream options — Tinder, Bumble, Hinge, OkCupid, Facebook Dating — are all there but they're built for relationships with heavy moderation.
I switched to Datewander a few months back and the quality of interactions improved noticeably.
That's my honest take based on actual use, not just reading about it.
