I think a setup that would work well for Nintendo is not necessarily going after hundreds of third party titles for a "Switch Pro" (hypothetical).
What you want is just to add some more appeal/breadth to the portable console concept, you don't need to get into a pissing match with Sony/MS, especially when you already have Nintendo's big IP.
I think you'd want to add a few franchise entries like Kingdom Hearts 3, Call of Duty (series), Grand Theft Auto V (w/online), Final Fantasy VII Remake, Resident Evil (main series), Assassin's Creed series (no streaming), Elder Scrolls VI, Star Wars Battlefront, Dark Souls III as Pro-only titles.
That's about it, it wouldn't necessarily be about suddenly competing for hundreds of titles. You just want to add a few of the bigger industry IP to increase the appeal of the unit.
I think Kingdom Hearts 3, Resident Evil 2 Remake, Call of Duty, and GTAV would all potentially be million+ sellers on the Switch which would make a port worthwhile. It's not about competing or getting the same numbers as what Sony/MS get, just expanding out the appeal of the ecosystem and I think there is certainly a market of people who would like to enjoy games like that on the go.
A Pro model can run a few of these IP and then it can run all standard Switch games (which would make up 95% of the Switch ecosystem for a while) at a better resolution and frame rate would sell quite well for Nintendo at $349.99, lets say (normal Switch, die shrunk to 14nm goes to $249.99 or less).
