I want to improve my understanding of literature UK - guidance please

Being 33 i not only want to improve my knowledge of things but I am aiming to improve my vocabulary too and just become a better person. I haven't learnt anything for far too long and simple things like exposure to my own language is actually quite difficult, I have spoken to equally low qualified people's and lived solely alone for 10 years and worked in a department on my own in silence almost for 5 years and now in my redundancy I have an opportunity while I can afford a break to have a little focus on things like literature and music. UK literature and in turn our culture mainly too so I can understand these key historical references too.

I was thinking of starting with some literature and then look at some historical things like time lines and the war of the roses amd other thingys etc currently while I do the house work it's either QI or time team on in the background.

Poetry- i known of William Blake, Shakespeare , Robert Burns, Yeats and Wordsworth but i couldn't tell you what they done without a Google. Do you think these are a great place to start regarding poetry ?

What about good reads? I have read Tolkiens lord of the Rings (will need a re read as there's a lot in there) but I love it. I'm fond of Agatha Christie Poirot, read Dorian Grey and never again. I know you can get these books that have commentary in or some notes, bit like a study book .. would those be useful too?

Can you recommend anything essential reads , texts, poetry etc even youtube channels that discuss people's works so I can learn these too?

This might be a sin to most but I have started my first ever audio book which I thought would be really difficult but no its quite good and helping with my listening I suppose - Son of the forest its a lore book based on a game.. but I need a next audio book, any recommendations?

Any free short courses mobile online you'd recommend for the fun of it?

Lastly I want to start a note book of literature type context of my favourite quotes or instances and on some add my side notes of what it is and why I liked it.

Your assistance would be appreciated 🙏 Hit me with a list and I'll most likely do it!
