I stopped using Traktor with my MC6000mk1 almost two years ago. So no clue where we are with mappings and jogwheel integrations now. I do know that Traktor seems to be “nudging” out non-NI gear from their offering. Again, not sure how it is for formerly officially Traktor certified gear like the MC6000mk1.
When I stopped using Traktor, with Serato not being an option (non-suppurted), I ended up with Mixvibes Cross (2.3 or so at the time). Still using that today. It’s full version (if you don’t need video, scratching or Pioneer HID) is 49 US/EU, which is the cheapest on the market I think. It’s features, imho, are great. So very handy things incorporated and flexible beatgridding (which was important for me).
Obviously the unit was also VDJ supported, so I am guessing you can still use that without issues too, albeit that the price of full VDJ is somewhat higher, so I think you really have to make a conscious decision to go with VDJ. If you are not sure, trying Cross before VDJ makes most sense (from a money point of view).
