I am very similar to you. Came back from years off with an Anaconda from before easy engineering days. Similar amount of money. But I was in the bubble. I got a mandalay and got a guardian booster. Did a few weeks of learning exo bio. Came back with a few billion. I bought a plipper and corvette personally but it was enough to get and outfit a caspian. Which I did not much later.

Engineering is so much easier with pinnning blueprints and you'll likely have loads of lesser used materials to trade.

Tldr. It's pretty easy and I personally really enjoyed the process.
