I believe you'll find the following helpful: (just search the name in Amazon.ca)
front underseat storage: temai (fits the front, not the back) very nice quality! A hard bin plus rubber insert.
back underseat storage: basenor (I put this at the back. Will block the floor vent, but works great otherwise. The driver side, there's a part of the seatbelt portion that will kinda hook into the bin. This will require you to put in the underseat bin at an angle to clear it.
rear center storage: basenor (just valcro to the back under the air-con part.
door side organizer: basenor (for the backseats, take out the original Tesla mat) (the original mat feels nice, but it's pretty flat, so it won't contain any spill)
console organizer: motrobe (this depends on your personal take). Many might like Spigen, but it's the harder material might make noise. So you want the felt version.
hidden armrest pocket: cusdusk (I like this design much more than all others. Others with the sliding cover, the cover might break easily. And it's hard to reach in to get stuff. This Cusdusk one opens magnetically, and very easy to reach everything, much more practical.
cup holder insert: temai (most others, when you take out your cup, it'll take out the insert with it, not so with Temai). Not the favorite color though.
glove box organizer: aramox (look for this design, the other design on Amazon is garbage and won't fit)
magsafe phone mount: magbak (this is arguably the best one, can route cable inside the trim)
floor mat: 3D Maxpider. Bought only because everybody else has this. Fit is perfect. Tuxmat should provide maximum protection. But I don't like mats that need to be installed with clips, which makes taking it out more complex (i.e. car wash).
cargo mats: kust. This is the ONLY single-piece mat that covers the entire trunk and the 2nd row seat back, all in one piece. Even 3D Maxpider will come in separate pieces. The drawback though, without this mat, you can open the sub-trunk cover and there's a spot to "hold" it. With the Mat on, you can't slide that into that slot, so you kinda have to open it up to a 90-deg angle and just let it sit there (opened). Getting into the upper sub-trunk you have to lift the whole back. Not deal breaker, but this should be the same for all trunk mats.
cargo pockets with covers: otrifowd. Perfect fit. And the covers match the Tesla too. The passanger side, I didn't think it would fit. The look is very confusing. But once you try it out, it's a perfect fit.
trunk/frunk mats: ldcrs. I don't see how anything more expensive can be better than these. The "frunk" floor is curved a bit. I'd say for the frunk, the fit is not 100% perfect, only because it doesn't "curve" the quite the same way. But once you put stuff on it to "push it down", it's all good.
mud flaps front/back: cyberbeans. I didn't know the Telsa would come with front mud flap. So I only installed the rear. Perfect fit. This is an actual "flap", not the regular mud "guard". I believe this should be more effective. The material bends really well, so highly doubt it'll ever break.
air vent covers: taruimoo. Really, just buy the cheapest valcro one you can find. Just don't get the hard plastic ones.
Visit EVACA, and buy their inlet vent cover, which will prevent leaves from getting into the air-con. Also, the front hood weather strip can protect things from getting into the frunk area. Easy to install, all perfect fit.
I got the Drop Stop seat gap insert. This prevents things from falling through the crack. This is so good!
