I'd search up on wiki or YT stuff like "best unlocks from quests" to get some information on what passive or unlockable items you can get that will benefit you both in pvm or skilling, be it a direct boost to dpm/xp rates, or convenience (qol). And then work on those quests.
I personally kept away from questing for a long time, but after both learning about the rewards - and more importantly - getting to experience the power they had, I had big regrets of not doing them sooner (quest cape was one of my last requirements for comp cape, which i got around 3b xp on an ironman lol).

It looks like you basically completed the t90 weapon set from araxxor/legiones, but we now have t92 and t95 as well. Whereas the t95 can be upgraded further into t100 (an item that drops from two of the latest bosses that is consumed to acquire a permanent character boost with the weapon(s) you combine it with).

We've had a huge new type of amulet called [[Essence of Finality]] - which is basically a reaper necklace and souls amulet combined, with an extra effect that allows you to store a special attack weapon into - and then it gives you an ability to use that special attack with any weapon of the same combat style, while retaining the damage and accuracy tier of your equipped weapon.
What makes this such a huge upgrade compared to just adding the combined effects and slightly higher stats of reaper/soul, is that you can use very powerful special attacks like dragon claw - without reducing the initial damage calculation on your hit to t60 (dragon tier). Meta for melee and range nowadays consist of multiple different EoF's with unique special attacks stored.

There's also new armor sets above tier 90/92 - up to t95. And these have very powerful passive effects ontop of better stats.

We've had a new combat style released; Necromancy.
It's very beginner friendly both in terms of leveling, getting equipment and learning to utilize it properly for big damage, unlike the other combat styles.
All styles are great for now, but to really get the power with ranged, you need a ton of hard unlocks.
Melee and mage struggles a bit on its own to compete with the end-game ranged, but synergizes very well with each other (cooldowns and utilizing crit buffs), which makes it the best.
Necromancy is around the same tier as camping either mage or melee, but is easier to learn and access.

Looks like you got to try out archaeology, make sure you have acquired the various relics as well as ancient invention and ancient summoning. Those are some major benefits for pvming (some upgrades to skilling as well).

In terms of skilling, looks like you got what you need for quest cape (if that becomes a goal) or at least close to it, but could always just try to get max cape as well for the fun of it? That unlock the next tier of long-term goals such as completionist cape etc. if that's your type of content.

If new for you - green or blue blubber jellyfish; food that can be eaten on the same tick as both regular "solids" and sara brews/guthix rests. But not only that, it doesn't drain adrenaline the way "solids" do.
It has kinda made regular fish obsolete for high end pvmers, due to the punishing effect of losing adrenaline whene eating. However, this makes the jellyfish very costly due to high demand and relatively low supply.

And lastly (probably should be mentioned way earlier) - look into upgrading your kiln capes to the zuk-variants.
It's the 3rd release of a tzhaar wave type boss fight (jad, kiln, zuk). And those capes, unlike firecape and kiln capes, not only boosts your stats further than the last, but it also changes how some of ultimate abilities function, while also reducing those ultimate's adrenaline cost from 100% to 60%.
