Logic has such a long history, it's not surprising that it shows it's age, and has 'weird' behaviour that you wouldn't choose today. It's got stuff in there from the early 90s, as it started out as a midi sequencer before pulling audio into the product.
It feels like the audio code was not touched since emagic days.
Every other modern DAW does this automatically. In Logic, you are expected to do this manually every time you do an audio edit. Like it's 2004 again.
Edit: added clarification about zero crossings and editing workflow
It's editing 101, check your cuts are at a safe boundry of put in a fade. I've never seen an auto feature do what I want though and need to redo it anyway, so just doing nothing is half as much work.
I would much rather complain about lack of AAF support in logic but then again I would never recommend logic to anyone other than for music production work purely because that's the only use case the devs seem to care about.
However when you zoom in in the Arrange the way the waveform is rendered it seems like you are cutting on a zero crossing when in fact you are not.
It lies to you and leads you to believe you've done the right thing.
I have had the pleasure of working on tracks with dozens of clicks that I had to remove thanks to the laziness of Logic developers, pardon me for dying on the hill and spoiling your view.
There's many things I disliked about logic when I tried it and that led to my opinion on its only useful for music production, I would probably not even say editing...
More on the composition level. If I'm tracking it's into Pro Tools, any edits happen there too. I personally don't move out but other's do really prefer to do more production work in Logic so I would happily bounce out tracks for them. Ironically AAF would solve that problem too...
Regarding cuts on zero... I basically never do so all my cuts will have a crossfade, generally the real world is just a little too chaotic to have a zero crossing just about where I would prefer the cut...
And if they don't well, more work for them.
Or just add it to the bill, if you are clear upfront that it will add $$$ there's no issues there.
I've had sessions rejected by mastering engineers for stuff that I've had to correct, why make this your problem.
For making demos and filling-out sketches, I'm thrilled. Here's the audio, and all rough playing, bum notes and general incompetence are my own.

Fun toy, though! I take it you extended it backwards into an intro, or you have playing it can read that you muted, leading into your guitar stuff. Did you play to a click or is it reading your tempo too?
I was pretty impressed, though, for approximately ten minutes start to finish. I should probably go recall what I played so I can try and finish the riffs off or something.
An actual competent musician ought to be able to make the most ridiculous demos with this thing.
