If you live in the right areas - mostly the western US - try JSX. Runs about equal to maybe 20% more than commercial domestic first class. Regional jets, all 1+1 seating, fly out of (effectively) an FBO, show up 20 minutes before domestic and 40 before international flights. Light screening, no terminal, no carryon (all bags brought off immediately at end of flight for collection planeside). Free WiFi on board and 120V power outlet at every seat.

I feel the need to praise the (relatively) new SFO terminal 1 somewhere. The design is a breath of fresh air.

Always my smoothest airport experience by far. No checked bag, Clear + Pre Check, fill your water bottle after security, get a coffee at Ritual, buy a banh mi for the plane, use a pretty clean bathroom, sit in one of those swivel chairs, get on the plane.

>40+ minutes of security theater

This is such an exaggeration. Usually it's like 3-5 minutes.
