Do you have some suggestions on what sort of sortiments you like? It seems like many of the common component assortment kits readily available, while having several hundred pieces, only have a handful of any particular value component, which tends to run out rather quickly after only a project or two.
Just get one of those where you have ~10 to 20 of each and get replacements for the ones you suspect to burn through fast (e.g. 1k, 4k7, 10k, 100k and similar common ones). But them in a drawer and refill when you need it.
I had one from a German reseller that doesn't exist anymore. For the university I made my own sortiment buy buying resistors and sorting them into boxes myself. It took 4 days to sort it, which is probably what you pay for when you get a sortiment.
My general approach is to start with a small-to-moderate assortment kit, and after each project restock the bins that are running low/empty with individual-value orders of 100 components or so-- Those are the values you're using a lot of, and so it makes sense to stock them more heavily.
I'd also recommend getting a kit of fixed-length jumper wires; it's much easier to analyze what you've built and turn it back into a circuit diagram when the wire connections are short enough to follow at a glance instead of chasing wires through a ratsnest.
Breadboard specific cut and formed wires such as these: https://www.amazon.com/AUSTOR-Lengths-Assorted-Preformed-Bre... [1] will make both wiring, and verifying, bread-boarded circuits much easier. Plus the actual circuit will be much neater with these wires interconnecting everything.
