More complex wallets like Electrum gives you better leverage to generate more and if you import your seed phrase on it you can more likely generate as many as you would want. Although, the electrum wallet is an hot wallet, I don't know how many addresses other cold wallets aside Trezor can allow users generate.
Electrum is both a hot and cold wallet depending on how you choose to use it. Its default gap limit is 20 receiving addresses and this can be changed and configured to a user's liking. Still, you don't need to import your Trezor seed phrase to take advantage of the extended gap limit. You can connect the two and create a new wallet in Electrum with your keys remaining safely on your Trezor device.
About gap limits.
Software like Trezor Suite and Ledger Live try to make it as easy for their users as possible. That's why there are limits to the number of unfunded addresses that you can create at the same time. On Ledger Live, I think you can only generate one per account (derivation path). The next one only becomes available when the previous one gets funded. On Trezor Suite I had no issues generating 2-3 at a time.
Could Trezor Suite allow you to generate 50 at a time? Sure, but you might have problems in the future. If you recover your wallet on a different computer and begin scanning and syncing it, Trezor, Ledger, Electrum or X wallet won't see your coins located on the 50th address in the gap limit, for instance. You would have to manually configure Electrum to scan passed the initial gap limit in its settings. Inexperienced users might not know this and they could believe they have the wrong seed and that they have lost their bitcoin.
