I had a laptop with a replaceable CPU. By the time it was worth upgrading it made more sense to buy a new laptop rather than upgrading the CPU. For repairability it's also not really that different unless you're running something like a framework laptop and, even then, replacement mainboards cost about as much as a whole new laptop anyways.
I do wish the M* laptops had something like a CFexpress slot or similar though. The built in storage is blazing fast and power efficient but soldered. Thunderbolt or USB drives are plenty fast enough these days but the external nature of the ports is a bit of a pain. Large amounts of storage are also where the price inflation really is (since you can't just add cheap storage it has to be the blazing high end storage + markup) so this would help the most.
RAM I'd rather have soldered in these days on a laptop. Performance is higher, power usage is lower, and you can order it with enough that you don't need to wait for new modules to be invented to upgrade and have enough RAM 5 years from now. It does mean you can't take any old M1 from ebay and upgrade it, which is definitely a downside, but for a laptop I think the benefits outweigh the cons. One thing I've noticed is there are always people that order them maxed out and move on when the next generation comes so high RAM options are still available used. One thing that is lost is, again, you can't choose to cheap out and get bottom bin speed memory. You have to pay for 8 channel 6400 MHz RAM in your laptop. Not necessarily a problem with the manufacturing method, it's possible to solder cheap RAM, rather just an Appleism. On the other hand... you do always know what you're getting if you buy one, which could be a plus.
Anyways, all of this is to say if you want a budget laptop which minmaxes it's price/performance ratio at a lower cost then the Apple laptops are definitely not the right pick. The reason for this is not as much how they are manufactured rather wher Apple targets the platform. The best price/performance optimization is probably a Chromebook with a monoboard and soldered RAM.
