That's essentially DS levels, which isn't unreasonable given the Switch is more handheld than home console.
I would say first and foremost a stronger lineup of exclusive (new) first and second party games. And ideally some of these should be big mass-market hit type games like Warioware, Nintendogs, more Mario Kart, Wii Sports-type game, maybe another fitness game.
New Model - a "pro edition" as well as more variants on the original model (maybe bundle them with games and make them a bit cheaper, more internal storage, etc)
Might go without saying but - at least a couple of price drops
Just continue to support it in some fashion so that it has a 7-8 year lifespan. That's not to say they can't crank out the next gen hardware but they should still be releasing games for it well into 2024 and even perhaps 2025.
