I recommend against this kind of framing. It comes off as judgmental. My mental models form based on my needs and experience. They're just as valid as your mental models, needs, and experience. Your way of seeing my perspective leads to faulty assumptions about my experience and models.
For example...
>> "I would agree, re: rough edges, if we were talking about Ardour 2 or 3, which both missed some important features and weren't as stable as I'd like. But in the last few years, ardour has improved. I do most of my work in it now."
I tried 5 from Mint's repos. Yesterday. I try every version to see if it'll work for me. Ardour continues to be critically lacking for me, based on my needs. Take a step back any time you want to assume someone's view is based on not knowing something you know. It's much more likely you don't know what they know.

LMMS also has its own percussion synth.

As for samples, Echo Sound Works sends out occasional freebie packs on their newsletter. Their samples are usually good.

Black Octopus Sound has a huge sampler pack that you can use in commercial stuff.

Also keep an eye out for SFX packs around GDC (Game Developers Conference). Sonniss publishes one every year. You can probably find the (legit, official) torrents for past years.
LMMS is good though. I must have made 200+ songs in it before switching to Reaper. I could get by with LMMS and the included synths if I had to. It makes me wish Reaper supported LV2.
They sorted through the fees and got things turned back on by explaining the situation, but it was a nightmare. Precarity is hard to understand if you've never been in or near it, or if it's a distant memory for you. It's overwhelming on a good day.
