I don't use the milk frothing wand in part since I'm too lazy to clean several pieces after each use.
For the most part, you don't need to do this every time. It's enough to just clean the residual milk off of the wand, and even then you can get away with letting it sit between uses (assuming daily use). You do want to maybe once a week or two just run hot water through the wand to clear any internal blockages, but it's not an involved effort. So long as you're keeping up with descaling every month or two, it shouldn't run into much trouble. You'll also probably fuck up using the wand at first, but it becomes super-intuitive after a while. When I first started, I had it too close to the wall of the frothing pitcher, and it was making this horrible resonant sound that was so loud I had to use earplugs. Obviously, that's just holding it like a retard.
Just-milk usually has an uninteresting taste unless you're making macchiato, so I often-enough will use a little syrup. Torani is cheap-enough, easy to find, and suitable for starter-level, but Monin is the good stuff. I normally put it in the steamed milk before hitting it with a frothing wand, but I like the physical sensation of milk-foam so even then that's skippable. I also highly recommend
espresso pucks if you don't already have one - they make cleanup of the tamper between uses a godsend. They're supposed to affect the balanced pour of it, too, but I think that's just marketing BS.
I'm trying to test different brands of ground espresso to find which ones I prefer
I'd say they're all going to create fairly weak espresso, because that's just the nature of pre-ground coffee that appears in supermarkets. But you're right that the majority of coffee grinders don't do the trick - they're built around pourover coffee, and they're both unfit for either coarse methods (cold-brew, french-press) or fine espresso.
I dropped a decent chunk of change on a conical burr grinder, which has variable settings for coarse->fine (though I still prefer a hand-grinder for coarse). They go on sale kindof regularly, though, so like any expensive coffee purchase you want to wait until it's randomly got a discount slapped onto it if you spring for it. The other annoying consideration is that if you go off-brand (which you should, the on-brand coffee appliances all have ridiculous markups), getting replacement parts can be a real pain in the ass. As a result you want to be semi-regular in upkeep on the grinder - oiling the gears, running some
SuperGrindz through.
It's a bit of work, but it's worth it. The taste of freshly-ground espresso is rich and vibrant, and you can absolutely notice the flavor of different blends peeking through. I still think stovetop moka gets this flavor stronger with a nicer texture, but the machines still do a great job.
Coffee doesn't really make me awake, nor does it really mess up my sleep.
It wakes me up and it does fuck with my sleep, but that's why I stock both regular and decaff coffee for when the craving strikes after noon, lol.
