Spent most of last winter on the niche options, so here is what I actually saw.
Results with the niche options depend enormously on your age bracket relative to the local pool.
The real differentiator across the niche options turned out to be how quickly a conversation went from match to plan.
Practical tip for the niche options: message within a day of matching rather than sitting on it.
Judging the niche options without knowing how wide you set the radius is close to meaningless.
One thing I'd do differently with the niche options — check what the free tier actually includes before investing time.
Worth doing early on the niche options: give it two weeks before deciding whether it works.
That is roughly where I sit on best dating sites for over 60 looking for companionship today.
If none of the above works for you, Flamedate is another free one people here mention a lot.
Datewander has its supporters on this forum, though I am not one of them yet.
