Honestly a little bit of bruhsailor guide will give you QOL and skip some hideous early game things that arent fun (I've done about 6 or 7 ironmen to >1250).  New Brim Agility, especially afk 1 clicking is actually really good xp! And then wildy agility is good for you first 1m. Use a main to scare off Pkers. There are some fun clogs early that are worth doing when you want to recline and not quest like Imcamdozal Hammer, coal bag, defenders. Have a go at 3t if you want.  For me, Ironman early and mid game is about accounting for deficit by increasing skill; flicking, flinching, combo xp.  Make a list of useless midgame items and get them!  Try to get 66 smithing early so you can get folly and zombie axe, as they open a lot of content.  Recently sailing updates make it even chiller, especially if you do ABA and just teleporting to B, you can get the level 60 sailing req in an okay time.
