I am going to create a 2-3 multisig wallet with electrum.

Will I be then able to spend funds with other wallets than Electrum ? Or will my wallet only work with Electrum ?

Why? Even non-MultiSig Electrum wallets only work with Electrum.

Or are you perhaps talking about the seed phrase?
If so, the workaround for BIP39 compatibility is to create your BIP39 seed phrases somewhere and then import those to your Electrum during MultiSig wallet creation.
So instead of selecting "Create a new seed", select "I already have a seed" then tick "BIP39 seed" in the option;
There'll be additional step of selecting the script type but the rest of the steps should be similar.

Of course, the "other wallet" should also support BIP39 seed and HD MultiSig wallet.

Or not strictly seed phrase?
Because you can import the master private/public key(s) to Bitcoin Core via descriptors.
Here's the basic instructions on importing HD Multisig descriptor to Bitcoin Core: https://bitcointalk.org/index.php?topic=5427745.msg61426872#msg61426872
For Electrum master private keys, the derivation path is different. (it's a tedious thing to do but it's possible to import with the correct inputs)
