I like your cap system; to speed decisions I add the “would I buy this again today at full price?” test - if not it goes. Since shipping is slow, I only keep spares for things that would take more than two weeks or cost more than about $30 to replace; everything else follows the cap. One more trick: do a favorites-first pull - lay the whole category out, pick what earns a spot in the container, stop when it’s full, and let the rest leave without more debate.

Happened to me after a smoothie spill dried in the wrong spot. Unplugged it and pulled the jar off and and cleaned the interlock areas where the jar or lid meets the base. There are often little tabs or pins that need to move freely or press a micro switch. If they get gummed up, the blender thinks the lid is off and stays off. I used a toothpick and a damp cloth to work out dried residue around those parts, then wiped the rim of the jar and the base coupler. Let it dry completely, reseated the jar until it really clicked, and it woke up. If it has an overload reset on the bottom, press that once the machine is cool. Overheating can trip it after a heavy blend with lots of frozen stuff. One more quick check is the blade assembly. With the jar off and unplugged, gently turn the blade by hand using a towel. It should spin smoothly. If it is stuck or gritty, that binds the motor and nothing happens. No lights and no hum after all that usually means power is not getting past the switch or the internal thermal fuse is gone. At that point I would decide whether repair makes sense versus replacing, since motor or fuse work on a sealed appliance gets tricky. Dead silent otherwise.

Yes, you either want a case with the magnet ring or no case at all, and A thin case that only passes Qi power will charge but it will not hold alignment. If you do not want to buy a new case take it off at night. End of story.
