I have an older VPI Prime and enjoy it.
I think your other choices would do you well also.
Your choice of phono stages bothers me as you would be sending the signal from a $3k TT (more with cart) through a $400 phono stage. Maybe for the Mofi but not the Scout.
Bottleneck? The phono stage would be your limiting factor.
IMO the phono stage is just as important as the TT/cart and I would spend more on the phono stage than the TT. In fact my phono stage is the most expensive component in my system.
