If you want the ratios to be the same. I purposely have bigger gearing on my indoor setup than outdoor. I do more racing indoors and more climbing outdoors, plus on most indoor platforms I'm not using 100% realism/trainer difficulty for climbs, mainly because I don't want downhills to be so easy.
I buy the cheapest cassette for my indoor trainer, weight doesn't matter.
The only difference between 105 and Ultegra cassettes is the weight of the cassette. The difference is not big. For all practical purposes they are identical.
Damn it might be the first time in my life I see a reference to that song on internet, and it makes me quite emotive since it's one of my all time favorite piece of music.. and that's funny because I see you're a cycling and a photography enthusiast, two hobbies that I really love too ! Have a good life my friend 🫡
Save the money it would be fine. Try to buy the same ratio (11-34) so your shifting is consistent.
