Such a big question!
It's really a case of trial and error, as you've already found out.
As you say, there are a lot of lids from £30 up but it really is what you're comfortable with.
It's a pain that you try a lid and feel ok only to discover after riding for an hour, you hate it!
I didn't get my open face in the UK so I'd waste your time suggesting it.
What have you tried already?
Have you tried a flip-front?
Best of both worlds - most have detachable chin pieces so you have one lid that serves all year round.
