For transfer from Electrum, which is recommended?

Either BTC or BTC(SegWit). I would choose the latter, though. The transaction fee should be negligibly lower since SegWit outputs weight slightly less than legacy ones.

So far you want to transfer Bitcoin, you can either transfer it to BTC which means addresses that start with 1 (legacy addresses). Binance like a month ago or two support native segwit addresses which is BTC(segwit), they are the bitcoin addresses that start with bc1. Never send to the rest, or your bitcoin may be lost forever.

I will advise you to use segwit because it has low transaction fee, latest versions of electrum wallet generate segwit (bc1) addresses and if you send to segwit on binance, the transaction fee will greatly be reduced than sending to legacy addresses.

BTC and BTC(SegWit)
If you deposit your Bitcoins from your electrum wallet onto the addresses generated from BEP2, BEP20 (BSC) and ERC20 options. You may lose your Bitcoins forever since they are different blockchains.

1. BTC and BTC(SegWit) - Bitcoin Network, This is for the real Bitcoin
2. BEP2 - Binance Chain, This is for tokens pegged to Bitcoin on the Binance chain like BTCB
3. BEP20 (BSC) - Binance Smart Chain, This is for  tokens pegged to Bitcoin on the Binance  network like BTCB
4. ERC20 - Ethereum Network, This for tokens pegged to Bitcoin on ethereum network like WBTC, tBTC, rBTC etc
