Personally I don't think Prusa is really as far behind as some people claim. A lot of printers on the market are still single material bed slingers, and it's not like Prusa doesn't have a Core XY, it's just a large and expensive machine (Prusa XL).
Considering they have been in the market a long time and their printers are known to be reliable workhorses, I went with the Mk4.
If you're worried about that, then Prusament PETG V0 is a good option.
Pulling a full 15A is liable to trip a circuit breaker anyways, it's extremely rare to need that kind of power from a single outlet. The outlets I use can handle up to 1200W, but the Prusa Mk4 has a 240W power supply, so there's plenty of power to spare. I don't imagine even a Bambu would be pulling a full 1200W.

Another vote for the Mk4. I'm very happy with mine, and I think that some people who lash out against it need to consider that not everybody wants a speed demon. Some people want good support and high uptime.
I've got my smart plugs on Zigbee, through Home Assistant, so they're not on the cloud. But that did require some research so I could get the right devices, because it's a bit of a minefield trying to find smart devices that don't need to be cloud based.
There is a PrusaLink integration for Home Assistant, I'm using it.
I got an Ender 3 for Christmas, it was great - but it's limited if you don't get a bunch of upgrades. But I did learn a lot about how 3D printing works.
I recently got a Prusa Mk4, and I'm very happy with it. Prints like a dream, is much faster than the Ender 3, and is much quieter as well. Time will tell if long term reliability is as good as I've heard, but short term it's been very reliable.
I've heard a lot of people suggest Bambu for the same price - but honestly I'm pretty skeptical of how they run their business. For some reason, they encrypt log files. Their support staff gave Grant of 3D Musketeers a terrible support experience when he had problems with his printer. Recently they had a cloud outage that resulted in printers starting up unexpectedly and starting to print automatically, which in some cases resulted in physical damage to the printer when there was a previous print on the bed. I would wait at least a year for them to sort out their business.
I have a Revo installed on my printer, so changing nozzles is easy. Since the nozzles are standardized and are the same height, I don't need to adjust the Z height.
If layer adhesion is a problem at larger sizes, check the line width, it should be larger than the nozzle size.
Having samples makes it easier if you have a lot of filament, and in my case I have a bunch of cards in a box I can easily carry with if I get a request and want to show them their options.
I use this one. They're cards, you can print a box to hold them, they have text easily editable with OpenSCAD.
It's a trend, away from the plastic spools which were decidedly made from a non-recyclable plastic.
It's always been curious to me that recyclable plastic was never even considered to be an option.
That said - cardboard is recyclable and biodegradable, so it's good no matter how you dispose of it.
But - it does have environmental downsides. If not carefully sourced, the wood can come from places where deforestation is a problem. It's also rather energy intensive to make, so depending on the energy source can contribute to CO2 emissions.
Nothing will be perfect, but cardboard is likely better than the alternatives.
Been learning FreeCAD myself, recently switched to RealThunder's Link branch. It's not the easiest to learn, but I haven't come across any major limitations either. It's really nice to have software where you can do what you want and know you have full control over your documents.
I should never have to carefully read a EULA to know what I can and can't do with my own designs, or whether or not other people can access my designs without permission.
