After importing iphone photos to pc from icloud how can i delete the imported photos from both icloud and iphone simply in one action?

the end goal is hopefully that when I download from icloud to pc , then delete from icloud , that those deleted from icloud would also delete from my iphone as well at the same time, because i have about 10000ish photos and i have a feeling that going through on my iphone on the photos app and selecting and deleting will be kind of tedious and time consuming. Also, since my icloud storage is lower than the storage required for the amount of photos i have, i want to be absolutely sure that the photos i've imported are deleted after on both icloud and iphone - 1. so there can be space on icloud to make the next transfers and 2. so that i know im not getting duplicates when backing up the rest of my photos to icloud to repeat the process i laid out in the original question posted, or 3. that i accidentally delete photos that weren't backed up on icloud. So it'd be nice if deleting from icloud also deleted those same photos from my iphone at the same time to avoid having to do all this duplicate checking and tedious deleting manually.

But now thinking about it a little more, if the pricing isn't too unaffordable for more icloud storage i could just do that and move everything in one fell swoop then check that the photos/files number is the same on iphone and icloud and then on pc as well after downloading and just bite the bullet and go through selecting and deleting everything manually.

And thanks for the reply, you're idea is probably a good one going forward from here, i kind of f'd myself by being a photo hoarder and not just trying to figure this stuff out when i had like only 100 photos.

yes thank you this is a much better solution than what i was working with.

yeah thats part of the plan just in case of pesky cosmic rays or heaven forbid something happens and i only had all that stuff in one place , thanks for reminding me.
