Most of the popular accessible Wii games already have a counterpart on Switch: Mario Kart 8 Deluxe, NSMBU Deluxe, Animal Crossing: New Horizons, Ring Fit Adventure, Super Mario Party. You are setting a very arbitrary rule by saying that Switch needs a sports game in order to qualify for the same column when there's already a good selection of accessible games on the system. Being like the Wii does not mean to be exactly like the Wii.
Switch being successful because it's a handheld system is as shallow of an analysis as saying that Switch can't have a long lifecycle because Nintendo consoles don't have long lifecycles. Indeed, you are on the same level as a common anti-Nintendo troll.
I've said it multiple times before, a complete version of such a table would include handheld consoles. I can tell you where Nintendo's handhelds would be placed: GB/C, GBA and DS would all be Arcade Evolution, because those were the games those handhelds were about. The 3DS would go into Balance, because Nintendo's initial sales pitch bragged with IPs like Assassin's Creed, Darksiders and other games from American/European developers who started out with PC development. Some of these games were never released for the 3DS, but failure does not change intent, just like it does not do it for the Wii U where PC games got even more attention from Nintendo during the initial sales pitch.
This context explains why Nintendo handhelds were successful. Not because they were handhelds like your shallow analysis suggests, but because they were built on what made Nintendo a successful console manufacturer. The 3DS was only moderately successful at best and it's very likely that that is a direct consequence of Nintendo's different approach, because the pattern that is forming for Nintendo's ups and downs strongly correlates with their strategies.
Lastly, the IPs you named (Mario Kart, Smash Bros. and Mario Party) all sold better on the Wii than on the 3DS. And on Switch they are selling even better than on the Wii. I give you that Switch is bringing in the handheld gamers, because it obviously does. But at the same time the Wii crowd has been coming back, hence why we've already seen new franchise records for games long before they are done selling. Switch software numbers already look amazing, but these games are from being done yet.
You misunderstand my argument, so let me put it simply for you.
1) The words "accessible" and "arcade" do not mean the same thing. The game Defender was not considered accessible, but it was most definitely arcade. Likewise, "The Sims" was an extremely accessible game, but it was most definitely a PC game. If your argument is really about accessibility, then you should call it that instead of "arcade".
2) Even if you think these two words do mean the same thing, the Switch is not nearly as accessible as the Wii was. The main thing Nintendo found before they developed the Wii is that people hated the classic controller (i.e. 2 analogue sticks, 8+ button, etc... controller). Most Switch games use this as the default controls. The Switch is not selling because of simple controls. However, the Wii had Wii Bowling and Wii Tennis. All you do is wave a TV remote and the game works. The magic is not in the "sports" part. The magic is in the simplicity. People who would not play any other video game would still play Wii Sports.
There is no mega seller on the Switch that is as simple as Wii Sports. The Switch is selling to a different crowd, and that crowd doesn't really care about accessibility. I would be shocked if I walked into a retirement center and they were all playing Animal Crossing. I wouldn't be shocked if they were still playing Wii Sports, because no other game has come along to get them to buy a Nintendo system. Animal Crossing is selling to a totally different crowd. It's not pulling in the Wii gamers.
