Why don't you store all of the original images and videos on your iPhone? That way you can access them all regardless of your connection to the internet. For me that's the only reason I have 256Gb phones.
I don't really view photos or videos on my phone, other than to review a photo I just took.
I've used around 70gb of my 256gb. I don't use iCloud, but offload my photos/videos to my laptop which gets backup to my NAS, and a couple disconnected and off-line hard drives weekly. Current photo library size is around 90gb.
