I would say no, unless that is the kind of stuff you are specifically interested in.

You will probably never see a full adder chip outside of retro and tinkerer stuff. If there are commercial uses left, they might be gone and replaced by FPGAs soon.

If someone asked me to teach them the more modern way, more appropriate for someone who wants to make props or puzzles and stuff as opposed the more retro experimental stuff, I'd advise a bit differently.

I would probably tell them to start with an ESP32 powered Arduino module, and some op amps, because op amps are both easy to understand and practical.

And at the same time, brush up on your pure mathematics side stuff, if you don't want to be like me, not really able to do any of the super high end stuff.

At the basic level you won't even need algebra, as you do more advanced work the math gets heavier.

Before even touching a real circuit, go immediately to the Falstad Simulator, and check out their example circuits. No, it's not perfectly accurate, but it is an amazing tool and runs right in a browser.

I think there's a lot of stuff that is kind of cool to try out for educational purposes that might be best just left in the simulator, at least at first, so you don't have to buy a bunch of stuff just to try out, and then not know what to do.

Probably don't buy a name brand soldering iron, a Pinecil V2 is probably about what you want, or a random T12 station.

The current good cheap multimeter changes every week it seems, the no name stuff is always changing, IIRC right now it's the HT118 or something that a lot of people like, but I could be wrong.

Oh, and don't invent a brand new standard and decide you're going to make all your stuff compatible with it, make up a bunch of custom cables, etc. There's a high risk of being bored, or finding some new universal standard for everything, and winding up with piles of useless junk.

Just buy the parts you need for one project at a time. USB-C and barrel jacks are good. Don't use too many weird connector types, because cables take up so much space and are a really annoying kind of junk to have around.

Wagos and premade pigtails are your friend for making up adapters.

Learn the E3 resistor and capacitor values, see if you can keep to mostly just those, if you want to reduce the number of different parts you need.

Most intro tutorials don't cover a lot of this stuff I wish I had known....
