Would also add that where you are using is pretty relevant. Some work well in country a but not in b, at least this is the case with subscription based, as opposed to using private (self-configured.)
I think you already have a tonne of good suggestions. Proton is useful here but not where I was last year. Not sure what people have to say about things like Mozilla or Apple relay. Always here good things about MV.
ivpn looks interesting but haven't had time to test
