Before Garage Band, I used Tracktion (I think its now called Tracktion Waveform Free) in the same manner. It's been ages since I used it but if you're a Windows or Ubuntu user I think it'd be worth checking out.
I use Reaper as well, but it takes a while to get that "useable" for modern(ish) music production. The benefit is there's plenty of free virtual instruments/VSTs to download. All of them have downsides though as does reaper itself. In Ableton I can make an EDM track relatively fast given the out of the box presets - especially synth drums - but in Reaper using a free VST like HELM makes it kind of a pain to use. YMMV.
No matter what you choose, I do HIGHLY recommend downloading Spitfire LABS though - the free instrument packages are massive and highly customizable. It's truly amazing.
Here's some good VSTs for Reaper:

EDIT: oh also trying to master a track in Reaper with free plugins is frankly pretty bad for a beginner vs Ableton's preset limiters and other utilities. The Cuckoos plugins are messy to deal with in my opinion.
But having said that, sometimes the thing that grabs the interest is recording your voice in the windows built in recorder then playing it back backwards. Try audicity?
In the same vein, the Novation Grooveboxes[1] offer some expanded capabilities that don't require a computer. Second-hand pricing is quite reasonable for both.

There is a big community around REAPER also, and tons of YouTube videos around it. Plus, you can download it and work with it for free, but after a while, it will want you to pay for it, which is only $60...but you can keep using it if you don't (though I would encourage you to pay for it if you like it).
If you've got an iPad that's probably the best start (it'll run on any iPad 2 or above). It will run on iPhone's but it's a bit harder to play. There's also a Nintendo Switch version (it's more limited, eg no audio recording or export), and a mac version (but it's pricey). Annoyingly, the Mac and iOS versions are separate, but at least the iPhone and iPad versions come together as one purchase.

Oh, and samples? Kids used hardware samplers to rip or record their own:

And how'd that work out? The end result was a piece of music called a module ("mod"). Strangely enough, I can't find exact (or even approximate) numbers. A snapshot of the MOD archive from 2007 had 120k mods:

So, yeah, a very low barrier of entry... ;-)
I was planning to try Reaper or FL Studio.
My biggest complaints with LMMS are: doesn’t support VST3, can’t see notes for multiple tracks at the same time (although I saw a “ghost notes” patch someone was working on for this scenario).
Unfortunately the open source DAWs don't hold a candle to any of the paid ones. But once you're paying they're all pretty solid. It's like asking if you should move to vim or emacs or jetbrains after starting with Notepad++. They're all good and everyone will have their own favorite. Many people also use multiple DAWs the same way people use multiple text editors. Personally I use Ableton and Reaper
Really, it might make the most sense to just find music similar to what I've made (or want to make), and then ask/research what they're using. Edit: I think that's how I originally found FL Studio and Reaper, come to think of it!
