Does "- a P2WPKH wallet is required; this type of wallet is now the default for standard wallets" or "- P2WPKH addresses are required; this kind of addresses are now the default for standard wallets" sound better? Either should be more understandable for most people.

The former sounds right, the latter suggests that a single imported P2WPKH address/key can be used for LN.

Tried it and the "enable" button is disabled for imported wallet with a single native SegWit address.
But it might change in the future because of this message when I clicked help:
