Hey cessnockles , welcome to the forum. I guarantee you'll learn a helluva lot here.
As someone who has created many allgrain brews in the past and currently scaled back to cans and bits.
I'd say the liquid yeast thing may not be that worthwhile until you go at least to the "specialty grains" level
For cans of goop I have found quick and reliable fermentation to be the key.
If you want a quick ferment with liquid yeasts, you'll need to make a starter around 3 days before you start your brew.
If you are new, I'd stick to US05 or Nottingham and if you've only got 1 fermenter - go buy another one.
After a few days once the bubbler slows down to a tick a minute or so, rack it to your second fermenter, leaving most of the trub behind.
Do everything you can to avoid oxygenation when you are racking e.g. use tubing to drop into the base of your 2nd fermenter
I even squirt C02 in the fermenter first.
This will likely improve your brews far more than a liquid yeast would and is simpler to do.
Obviously you WILL use liquid yeasts as you progress and start to try and brew more exotic beers.
The greatest improvement to cans is adding flavor hops - something I always do when moving to the 2nd fermenter.
There are lots of recipes here you can follow and they are all pretty good.
Don't ask me for my BB Pale Ale can recipe unless you grew up in the UK - it's a warm low gas abomination based on a Coopers Pale Ale can - I quite like it though
Good luck mate.
