Muun is a good choice as on-chain wallet that can occasionally output lightning transactions, through painless (but sometimes expensive) submarine swaps. If you're onboarding newbies for the first time just let them download WoS, stressing the fact that a custodial solution is NOT the best way. Later on, when they get a grip on Bitcoin, point them towards Phoenix and let them build their first hardware wallet with Seedsigner (also a fun activity to do together, with great educational value).
