Raspberry Pi to loop Slideshow

I'm looking to buy a Raspberry Pi to be used in a reception TV screen to loop a powerpoint, I saw a few ways it could be set up and wanted to ask for advice on what model I should buy and any tips on setting it up. I will most likely use Raspbian and LibreOffice to set up the powerpoint, and as the people who work here aren't tech savvy I was wondering if it would be better to set up a VNC to remotely control it. https://thepihut.com/products/raspberry-pi-starter-kit?variant=20336446079038 Would this kit with 4GB RAM be overkill, or would another Raspberry Pi be more suitable? 2GB would be fine for playing videos but just being considerate of scaling or any other uses down the line, but those are unlikely.

You could also make a export of PowerPoint to pictures or html and then just have firefox in "Kiosk mode".

yea that's true

if there's things like transitions and what not would that just have to be a video?

i think the site the slideshow was made on can also be hosted online so maybe i could run that on the pi
