Since I don't have my new Model T yet, I was watching some YT videos. I bought the Model T so I can see/access my Cardano on it.
Do I need to go through a 3rd party website to actually do that?
Daedalus, Yoroi, and Adalite?
dkbit98 has answered this question correctly, you will need AdaLite or Yoroi wallets. For more help, you can use this below link,
Cardano (ADA) - Trezor Wiki to know the procedure of how you can use AdaLite which can also be helpful while connecting Trezor with Yoroi.
