Imo SP isn't that important. If you just play the game normally you'll have a massive surplus of most resources excluding edge-cases like tellurium, hexenon, and mutagen samples (if going for hema). Faster faction rep is nice, but you're also capped anyway, and ime the SP bounties in the open worlds are so much slower until you really take off that it's not even usually worth it (disregarding entirely that randos in public lobbies will generally do a much worse job). Acolyte arcanes and more arcane adaptors are nice, as are incarnon adapters, but you can easily get by even late-game with more easily accessible ones like the Laetum.
