The Pacifica is a genuinely decent instrument (I bought one (not pink!) a long time ago and they're still made and still good value for money). The 'LA' is a no-name "built to a price, could be ok but who knows", type instrument. You pays your money and takes your choice. I'm guessing if colour is a big factor, what it sounds like may not matter.

Your best bet might be a local music store that will be desperate for trade and a deal.
The little battery Blackstar is a nice little thing, but it doesn't make an electric guitar sound like, er... an electric guitar. It's just a clean, no effects output. That's why the guys are linking you to something a bit more expensive with onboard effects.
One option to consider (sorry to complicate things) is something like this...
https://www.amazon.co.uk/Zoom-G1on-Guitar-Effects-Pedal/dp/B00HS3DHCU which I have, but seems to be unavailable now. The output from it can be used with headphones, or you can use a normal audio lead (with headphone adapter) to plug into any audio kit in the house (maybe even a bluetooth speaker) that has a line-in socket.
https://www.andertons.co.uk/zoom-g1-four might be the replacement available now, but I don't have time to check reviews and stuff. The living room is a tangle of Christmas lights and I want to get to bed some time before 5am.
Oh, and whatever you buy, remember a guitar lead!
