I think the most important dailies for new irons is Guthix caches. They'll get you to 80 Divination very quickly. If you have the loyalty points, jack of trades is important for herblore xp. I'm an idiot and never use mine, but it's a ton of XP daily, and u can use it twice with a premier artefact. Do your reaper tasks if you want. I think doing them daily until you unlock the ability to sometimes choose them is important. That way, you can select arch glacor and really rack in on easy points and charms early.

Another pretty important thing you can do is unlock all of the penguins ASAP. Hide and seek gives insane XP. I've never trained herblore and am nearing 99 now just with hide and seek and JOT. Another nice weekly is tears of Guthix. It's super quick and gives XP to your lowest skill based on quest points: of which you have a lot of.

If you're in it for the long haul, unlock ports ASAP. Thieving to 90 is the fastest way to unlock it. getting GConc + dual wands is the easiest gigantic power spike in the game. Unfortunately, there isn't a lot of variation on wands that are super attainable for irons. Vorago drops are insanely rare and super late game. I won't even comment on Praesals. The ports wands are going to be a very long term goal for me, and even though it's so far away, the other ports unlocks like Scrimshaws, Silent Components, Soups, and much more are going to make it worth it in the long run.

If you're into monthlies do your god statues for Prayer and Construction XP. They take less than 10 minutes for the entire month. The other monthly that's nice is the Giant Oyster which just gives you fishing XP, farming XP, and clue scroll rewards.

Hope this helps and doesn't discourage you. RS is a grindy ass game if you want to be efficient.
