If you generate a new wallet from Electrum, you will not able to retrieve your coins if you use other wallet.
You can import electrum seed phrase into bluewallet.
Sparrow also allow you to import electrum wallet files.
My main concern was that Electrum is using different standard, so when I generated new seed words there WAS some words that could be reconstructed in two ways if saved as 4 letter word.
Electrum and BIP39 use the same wordlist, but a different algorithm for generating seed phrase.
Electrum used a different wordlist in the past. Since new versions of electrum allow to import old seed phrases, electrum still suggests the words from the old wordlist.
"Ground" and "common" words that you mentiond in OP existed in the old worlist, but in the current wordlist.
The words used by BIP 39 are quite different from that of electrum.
No, electrum and BIP39 the same wordlist.
Their word list and checksum rules differs and if you try to enter a BIP39 seed into Electrum
it may consider it invalid and reject it
Again wrong. Electrum allow importing BIP39 seed phrases.
