Yeah, ideally you find someone who does both, Isak is probably a decent example. And anyone who has those traits is likely to have some sort of goal scoring record unless they're really young.
But I'd be weary of signing players purely based on their goal record. The pool of strikers or wingers who've got a great goalscoring record is quite small, and the number of those from that pool who'd be able to maintain it here is even smaller. If a forward player can near enough guarantee you 20+ league goals a season you're talking min 100m, Just count the ones you already have in the PL, Haaland, Salah, maybe Son?
Martinelli btw would be among the top of my targets for players with loads of potential to score goals. A 22yr old who has in the past scored 15 npg in the league. It's insane to advocate 'binning him' rather than finding ways to get him into goalscoring positions.
