Three things specifically (though one is a two-parter)

1. Nanch micro screwdriver / bit kit. I had one previous and I rather liked it but I gifted it to my brother who was just starting out with DIY maker stuff, so I replaced my old magnetic kit with one that has the bits lock into place with a collar. I love the quality on it and I'm glad I'll probably never need to buy another one again.

2. Lutron Caseta switches for my house. I haven't replaced the lot, but I've replaced the most commonly used ones and it's so nice being able to stagger to bed after a movie and just tell siri to turn all the lights off in the house.

3. The last is a two parter; dewalt makes a little cordless screwdriver (not really a drill). That has a ton of utility, but what I like best is that I can combine it with a cordless drill "cleaning attachment" kit that you can get off amazon (or probably other places). Put the two together and you can save so much time and effort scouring things - you still have to manually do some nooks and crannies, but you can get the vast bulk of it out of the way and let technology work for you. A regular drill would work, but it goes too fast and flings shit everywhere, while the screwdriver has a much lower RPM. This combo is just my favorite.

+1 on Lutron Caseta. Another plus with them as that you can get the remote and create a 3-way switch for your lights if you don't have one. I had the living room switch at the front door only. I changed the two gang wall plate at the kitchen to a three gang wall plate and mounted the remote in the wall plate. It is so thin that it can just set against the dry wall and no hole is needed.

I wanted to add 3-way switches to a few poorly-designed circuits in my house. I dislike the design of most smart switches, but this is what I went with after looking at a lot of options.
