Alright so for the fun of it let us compare the PS5 from November 12th, 2020 to June 2nd, 2024 (1298 Days) vs the Switch from March 3rd, 2017 to September 21st, 2020 (1298 Days) and see how the exclusives compare
So here are all the switch games on that list that are on other platforms:
1. The Legend of Zelda: Breath of The Wild - release on Wii U on the Same day as Switch
2. Mario Kart 8 Deluxe - 3 year old port of Mario Kart 8 on Wii U
3. Pokken Tournament - Port of a Wii U 2016 Game
4. You have Xenoblade Chronicless listed here twice in 2017 and 2018. I guess you are talking about the expansion that came out in 2018 and if your going to count that as a separate game you might as well count Horizon Burning Shores on PS5 then
5. Bayonetta 1 and 2 is a wii u port and bayonetta 1 is one 360, PS3, and steam
6. Hyrule Warrirors is a Wii U Port (It also had a New 3DS version but I'm not sure if that counts as the same game.)
7. Sushi Strikers had a 3DS port on the same day
8. Donkey Kong Country TF is a 4 year old Wii U port that was $10 more expensive on switch (They also tried to remove the wii u version on the eShop when this released as well.)

9. Captain Toad Treasure Tacker is a 4 year old Wii U Port but even if you count it as a new game on switch because of the Odyssey content, the Switch port also released on 3DS the same day as well
10. Octopath Traveler is on PC and Xbox One as well. For some reason this never came to PS4
11. WarioWare Gold 2018 is a 3DS? I'm not too sure why you included it on the list?
12. New Super Mario Bros Deluxe is a port of a 2012 Wii U Game
13. daemon x machina got a Steam port on February 13th, 2020
14. Tokyo Mirage Session is a port of a 2016 Wii U Game
15. Pokemon Cafe also released on mobile
16. Kirby Fighters 2 just missed out as it released on September 23rd, 2020 (which was Nintendo's 131st Anniversary)
17. Pikmin 3 Deluxe is a Wii U Port
18. Part Time UFO released in October of 2020 so it missed out and also has an iOS and Android ports
19. Super Mario Bros 35 released in October 2020 so it missed the cut off date
20. Mario Kart: Home Circuit released in October 2020 so it missed the cut off date
21. Hyrule Warriors released in November 2020 so it missed the cut off date
22. Fitness Boxing 2 released in December of 2020 and missed the cut off date
Now there are three games on that list I'm not too sure of:
Mario Tennis Aces- This feels like what Mario Tennis Ultra Smash was suppose to be but Nintendo needed a Holiday 2015 game so they released an early build of Mario Tennis Aces on Wii U
Another is XenoBlade Chronicles 1- This already was remastered on New 3Ds and it's how I played and beat the game back in 2016. I now this is extra remastered for the switch but should this really count as another switch exclusive?
Lastly Super Mario 3D All-Stars is literally ports using emulation to run SM64, Sunshine, and Galaxy, Should this really count as a new game?
That leaves you with:

and lastly Super Mario 3D all-stars
which is a long list but not many heavy hitters in it besides Animal Crossing, Luigi's Mansion 3, and Mario Odyssey But a couple years from now how many of those games will get Switch 2 remasters and get kicked off the list of exclusive switch games.
Also some of those games like Super Smash Bros and Splatoon 2 had help of quick development thanks to The previous entries on Wii U
