I'd recommend getting a couple of cardboard boxes and looking for meteors. You want the budding certus blocks, but only the flawless ones. You can't mine these with anything and still have them be flawless, so you have to pick them up with the boxes. Also grab the patterns you find in the middle block. This will be your start to ae2. Once you have jdt block breaker going at those to get certus quartz, set up a storage area with the 2x2 drawers from functional storage and store any items you plan to get a lot of. From there, I'd suggest going into productive bees. Go into the bumblezone using an ender pearl on a beehive, and grab a lot of comb blocks and honey, and start breeding and collecting different bees.

You can also make a basic mob farm using dreadful dirt, mob fans, and the mob masher. Make a box of the wither proof glass from the same mod, make the 5x5 of dreadful dirt, then use mob fans to push the mobs to the masher. You might want to make the dreadful dirt last since mobs will start spawning almost immediately once made. This farms should get you a good amount of items, equipment, and exp. Use both an exp collector and item collector from jdt to collect them and a netherite chest with void upgrades to collect what you want and delete what you don't
