Yeah that can help. I took another look at Trezor's coin page. For example, if your search for bitcoin or ethereum, the site only shows you Trezor Suite as the supported software. But if you type in polygon, then it displays 3rd-part software like MyCrypto or MEW. I guess if the asset is supported by Trezor Suite, they don't mention alternative wallets. If not (like in the case of polygon), they do.
Wallets listed are Electrum, Exodus, MetaMask, MyEtherWallet and MyCrypto wallet. I do not know if MyCrypto wallet support many other coins because I have not used the wallet before.
I have never either, but I think it's similar to MEW and only used for ether and ethereum-based tokens.
The last time I downloaded Exodus, it is supporting many cryptocurrencies including Solana and NFTs, although it is a close source wallet.
Yeah, Exodus is a multicurrency wallet, meaning that most coins and tokens would probably work by connecting your Trezor to it. It's closed-source, but your open-source Trezor does the sending. Exodus is just a means to get coins from A to B. All transaction details will be displayed and should be checked on the HWs screen.
