For personal transport I really don't see the need for super fast, etc.
So I'd find a WW2 bomber of some ilk and restomod it so at least the former bomb bay could carry a few people in comfort.
Or since I like to fish so much a floater of some type, like this Albatross -

For cross ocean, etc (something I wouldn't really be doing I don't think.... don't dream of it now....) I'd just charter.
If I had a reason for go-fast single person that same website above has a few Mig 21s and a F4H Phantom listed.... I'd be willing to learn to fly
