If you want privacy you should be using Monero. If you use Monero you can use the official wallet together with Trezor. In fact, if I am not mistaken you have to, because from what I recall the Trezor Suite has no support for Monero.

how to access crypto easily while at the same keep it private and safe?

These are conflicting requirements, true for all valuables: more accessible is less safe, more secure is harder to access. The solution is to split up your money in levels.

• Some hot crypto on your phone, like cash in your wallet. I keep about $100 of monero on my phone, ready to spend if I meet an accepting merchant.

• Similarly, leave some hot crypto on the exchange if you trade regularly.

• Some warm crypto on your pc, locked, secured, protected by dog and gun. This is like your checking account, ready to send to an exchange if fiat is needed on a rainy day.

• Everything else in air-gapped cold storage. Bury the seed phrases and tell no one. This is your "savings account", the stuff you will hodl and pass on to your kin, with no plans to ever sell.

Since by design cryptocurrencies aren’t backed by banks/nations and any transaction is permanent, they are by definition not safe.

At best, you can save out your wallet to an encrypted drive, then write it back to your phone when you need to use it. Make copies, so if one gets lost, you don’t lose the value itself.
