I endured reading with my (then undiagnosed) autustic, dyslexic DCs and it was painful. I also felt very much out of my depth as while they were struggling with words like was/saw (because the letters shuffled around to them) I was reading chapter books at that age and no recollection of the learning to read process.
I had a breakthrough with some Star Wars easy readers (DK) and also had some of my old Ladybird books. The Puddle Lanes had a parent page and child page, so the adult page was more prose to tell and develop the story and the child's page had a simple sentence on that theme. I don't know if there's similarly structured books still in print as they worked well. The Peter and Janes are still in print, and while they're not exciting, they are good for simple sentence development and non-phonetic sight words.
Some nights they were just too knackered to read and I'd just read to them, and if I was struggling on a busy night, poetry was an easy win.
By the later stages of junior school we were burned out with the pesky magic key and reading records, so I moved on to reading age-appropriate books like Harry Potters that they weren't reaching for and audio books of novels.
DS1 was assessed with a reading age of 15 on going up to secondary school. DS2 is age-appropriate, and both have well-developed vocabularies. DS1 favours factual content over fiction, and often reads his Warhammer Codex and lore, and that's the scope of his range of reading for pleasure.
It's hard because reading is so important academically. The system does expect a standard prematurely for some readers and leave children who struggle behind. Dyslexia doesn't tend to be assessed for before 8, and in many LAs only private assessment is avaliable. Some children catch up later, and some don't click easily.
I also recommend Alphablocks for the phonics. That was something we stratigically revisited and it did help.
