I have not yet found a telescope that does not work well with Tele Vue eyepieces. Tele Vue eyepieces simply work well in short and long and fast and slow refractors and Newtonians, SCTs, MCTs etc.
Tele Vue make a number of designs and your choice is then based on your apparent field of view preference as well as any preference for eye relief. I would recommend longer eye relief option should you ever choose to observe with glasses in whatever AFOV you prefer that is available for that option.

Note anything with the same field stop diameter will give the same true field of view regardless of eyepiece focal length. (Magnification will vary).
Yes you can spend a lot of time and money trying different eyepieces that have their focal plane curvature matching your telescope curvature or are an affordable match for a longer f ratio telescope but not for a fast telescope. You mention no budgetary constraints so I point you to what I believe is a product well proven in the field and one that is well designed, well tested, well supported and performs well in any telescope you are ever likely to own. You cannot go wrong with Tele Vue eyepieces (or their telescopes).
Bintel is the Australian dealer for Tele Vue and offer full warranty and excellent after sales support.
If you call Tele Vue you may even get Al Nagler on the phone. Have a chat and see what he says.
I have not listed anything specific but perhaps consider the Delos in combination with a 31mm Nagler and/or maybe 22mm Nagler too then Delos. This keeps your eye relief around 20mm all round. DeLite is another option for shorter focal lengths and narrower AFOV than Delos.
If you can look through as many as possible at any covid safe star parties all the better because each type has its own feel, even amongst the Naglers; Type 4 feel different to Type 5 & 6.
