2-of-3 multisig: minimum requirements and best practices

I’m exploring way to upgrade my security from a single Ledger hardware wallet (HW) to a 2/3 multisig setup.

What’s the minimum requirement for HW? Correct me if i’m wrong, but i shouldn’t need 3 physical HWs, should I?. Instead, i can set one wallet with one seed phrase at a time, then partially sign a transaction. Then reset HW and do it again with the 2nd or 3rd seed phrase to sign as the 2nd or 3rd co-signer. If that’s true, I think 2 HW devices (ie. 1 Ledger and 1 Jade) are minimum requirements for a good setup. 2 HWs instead of 1 for multi-vendor reason. Do I miss anything important with this setup? Instead of having a 3rd HW in a remote place and never need it except for possibly recovery, it’s cheaper and less maintenance to do away with HW and just safeguard the 3rd seed phrase (and its backup) instead.

Maybe there’s a flaw in this reasoning somewhere. I wonder why i haven’t found any discussion of this setup!?

Also regarding the recovery of a non-custodial 2/3 multisig wallet, what are the minimum pieces of secrets needed for recovery? I read that 2 seed phrases are enough to sign a spend transaction, but having those 2 only are not enough to recover your multisig wallet. What else does one need as a minimum requirement to recovery?

Please point me to a good guide for best practices. Unchained has good articles but more focus on custodial multisig.

TIA ????
