ledger-polkadot VS ledger-app-tezos

Depending on which Ledger device you're using, you'll want to approach this situation differently. Here is a list of Polkadot's supported extrinsics. You'll also notice there is a "light" version as well as an "XL" version.

Yes, you should be able to use nomination pools with Ledger on both Polkadot as well as Kusama if you have the XL version of the app.

There are custodial services that offer staking. They may allow earning rewards with a lower minimum stake. Again, do your own research, as some are only meant for non-Ledger accounts. Their staking process may require you to issue an extrinsic that Ledger doesn't support. You can find the list of extrinsics supported in the Polkadot Ledger app here.

Hi u/Sugarbird676, there are certain nested extrinsics that aren't currently supported on Ledger, due to the batch transaction making multiple calls in one transaction. You can find all available extrinsics here https://github.com/Zondax/ledger-polkadot

It think it might be related to this github issue: https://github.com/Zondax/ledger-polkadot/issues/134

Ledger Live exposes limited functionality. You could do a lot more with the Polkadot app (https://github.com/Zondax/ledger-polkadot) on your Ledger device by connecting it to Polkadot JS UI

see https://github.com/Zondax/ledger-polkadot/issues/110

I’m pretty sure the Polkadot app for Ledger was developed by Zondax and is hosted on GitHub (if you open the app on ledger you will see this referenced). Not much activity on the dev branch recently, and no mention of this in their issues.
