Maia is only 383Ly from Sol, and for maybe 150Ly of that distance you're still in the bubble. Get a fuel scoop, filter stars to scoopable ones, and you should have no problem - its is my no means either a long or difficult journey. I just took my Corvette back to the bubble for some refitting - 17Ly jump range, takes me 25 jumps (which I can do in about 30 minutes).
Do keep in mind that that outfitting is not great down here. You might what to think about what you'll be needing, then strip your modules back to storage, and then establish an FOB in a shipyard out here. Takes about 1 hour to ship modules from Jameson's, IIRC. I use Sister's Refuge in HIP 16813 as my base, mainly for role play reasons, but its a cool asteroid station.
Finally, you dont need to go all the way to Maia to encounter Thargoids - they just hit Exodus Point in Hyades Sector AB-W b2-2, which is only 250Ly from Sol. The point being, if you want to fight Thargoids, but dont like to travel, the Thargoids are now running a home delivery service...
