From that list I only know bitfinex but it is still good to know there are others.
It has to be pointed out that whenever you deposit Lightning Bitcoin on Bitfinex, it posts in your account as a seperate (LNX) token. That token has to be converted to Bitcoin on the wallet page and vice versa if you want to exit through Lightning. I find it a bit weird that they don't credit it as Bitcoin right away, but perhaps there is a valid (security?) reason for that I can't think of right now.
Coinbase will not stay behind, but there is no rush to the implementation of LN either.
They can bank on their first mover advantage and main fiat on/off ramp in the space for many more years to come. No exchange brought more capital into Bitcoin than Coinbase. I don't see that change at all.
It might not be that much of importance right now, but when the fees see a sharp increase, most people will look for an exchange with low withdrawal fees, which the exchanges that offer Lightning support can provide. Coinbase's fees peaked over 0.002BTC back in 2017 which is nuts. No way people will swallow that again while there are much cheaper alternatives available today.
