From someone who uses Lubuntu,
1- support
2- everything just works from the iso. Unlike other Linux versions, that certain configurations aren't supported, any 5-10 year old hardware until today is directly supported by the OS.
If you have really old hardware, you should try 14.04 or 16.04, which have backwards compatibility with much older hardware.
3- compatibility. Lubuntu 18.04 just works for multi GPU systems needing fan or power control over the GPUs. More modern versions don't.
If you like the search option in the start bar, I'd recommend you to try out Lubuntu 19.04/19.10
They're in essence the same as Mint in functions.
As far as Lubuntu's CPU support, they quote a 1.4Ghz CPU, but I once did a test, and it works fine with a single core 1Ghz CPU. Once you go below this, you may run into boot errors, due to the timer expired on boot file loads. (Meaning certain files won't fully load at boot,causing errors when operating the OS).
A dual core cpu of 1Ghz works just fine.
Also, Lubuntu moved from lxdm to sddm since 18.10, and should support it in their LTS (20.04).
