Fria Liga (aka Free League) has lots of niche tabletop games, although iirc, they focus much more on the RPG side than the wargaming side.
There’s lots of good stuff in the UK that I’ve found by browsing Kickstarter and small independent game shops online. I don’t what you’re into specifically, but there are lots of grimdark Mörk Borg inspired stuff out there right now that use system-agnostic minis for wargaming. Forbidden Psalm is one I’ve been pretty into for a bit, and I think they’re out of the UK.
Disclaimer: I have no idea what the gaming scene is like for a lot of these; I just have a bad habit of collecting indie games I’ll likely never play
