[Aarch64-laptops] Looking for a sportsbook that actually has good coverage for niche leagues?

I am getting tired of the same old mainstream sportsbooks that only cover the big leagues and ignore everything else. I follow some smaller European football leagues and also like to check out basketball games from leagues outside the US, but most sites either do not have them at all or offer such limited markets that it is not even worth looking. Does anyone know a platform that gives decent coverage to less popular competitions without making you dig through a million menus to find them?
