I think the Technic Lego kits that I grew up with (that were more about how things worked rather than looking exactly like the thing) have been rebranded as "Lego Education": https://education.lego.com/en-gb/shop/secondary/

They're pretty expensive, though!

Lego education used to be called "Lego Dacta". https://www.brothers-brick.com/2020/01/31/a-history-of-lego-...
