This desire for a true XC machine sounds like a thread that was born of your XC trip to Alaska!
And it sounds very much like the hunt I began last year (and I'm in an arrow too). What's the price limit? That seems like a dominating factor.
Aircraft that came up in my search that I still routinely check that I think check your boxes (
so long as your desire for more #UL is only for gas/range):
Columbia 400 (>=220kts, FL250, >1100 mile range, $300-500k -- most seem to be 3-4 range, Van Bortel + NexGA often have quite a few). Insurance quoted me 12k$ moving from arrow with 400k hull covg.
Columbia 350 (~180kts, 18k ft, ~1000 mile range IIRC, $250-350k). Insurance quoted me 9k$ first year on 350 hull covg.
Lancair Super ES (~190kts, 18k ft, >1000 mile range, $180-350k over the last several months, listings are scarce)
Mooney M20M Bravo (>200kts, FL250, >1000 mile range, $200-300k) [
There's other Mooneys that would satisfy your criteria too, I believe]
PA46... But I don't track these because insurance is absolutely insane for someone w/my hours+qualifications.
I've also often frequently looked at the Lancair Legacy RG and the nearly equivalent Glasair (>200kts, range >1000m, ~$150-230k). Small 2 seaters but fast as can be. And hey if your extra #UL is just for gas + range... these would check those boxes!
