Don’t bother buying stuff you “think” you’ll need except for a drill. Buy stuff beyond that as needed.

Depending on where you live get to know the deal spots around you: pawn shops, Craigslist, fb marketplace, ebay, etc. tools are frequently resold for fairly cheap especially if you ever desire stuff that’s a pain in the ass to ship/move like ladders/table saws/miter box/etc.

Brand doesn’t matter regardless of what internet dorks say for the most part but picking an ecosystem means you won’t have 90 different batteries hanging around. Keep in mind with some manufacturers there a sub lines with different batteries (eg ryobi has a battery whereas Makita has 3 different battery types).

Don’t buy Milwaukee. Dogshit tools that work okay until they don’t. Makita, ryobi, dewalt, Bosch, metabo, etc are generally repairable. Makita is my go to because you can generally buy parts (though sometimes cost prohibitive tbf), dewalt too but dewalt is pricier. Milwaukee though tends to have these proprietary pcbs with microcontrollers in everything for some reason that inevitably fail and cannot be purchased so once they fail the $350 tool you just got is junk. Whereas https://www.ereplacementparts.com/makita-parts-c-97.html? And https://www.toolservicenet.com/b2b/dewalt/en//Dewalt/OUTDOOR//p/DCCS623B sells actual oem parts

Harbor freight stuff is fine too especially if you’re not going to use it much (or even if you are, my palm sander is from there and I’ve used that for hundreds of hours. Had to change the brushes but otherwise fine).

Hope you know how to patch drywall.

If you want something like cameras that’s like a whole thing. IMO that’s where you should head over to selfhosted. Easy mode is get some WiFi cameras from whoever like eufy and slap them on your house but then you trade away privacy (uploads to their cloud servers and literally every company has had at least one “security whoopsie”) and connection stability (WiFi connection will inherently drop out several times a week/day/hour depending on your setup/congestion in your area. You go to check the camera and it’s always unavailable when you need it). You also have to either add solar panels to them or recharge them every few months. But this is generally what people do because it’s cheaper and easier

Alternatively you can get power over Ethernet cameras that have much more reliable connectivity and are more likely to run locally (eg record to hardware in your home, either an NVR or a server you make). Downsides here are more expensive (not subsidized by being able to sell your data + the cost of the nvr/server), needing to run Ethernet drops to wherever you want cameras, having to figure out something like tailscale if you want to view cameras remotely and truly don’t want any cloud involved
