I was very fond of Benjamin K. Shisler's website where he compiled his
Dictionary of English Phonesthemes.
His site helped me think about several ideas for my own conlang.
Sadly the site was hosted on Geocities which is now gone. But I did find two archive sites that seem to have saved copies of his webpages.
Totally worth a look! You will find there
lots of data about words that share an aesthetic association, or theme, with certain sounds, consonant clusters or vowels. There are
extensive lists. It's a conlanger's dream.
You could use these lists to help inspire you to create phonesthetic associations for your own conlang using your own phonology. Or it could maybe help you identify what sounds and sound clusters you find aesthetically pleasing in English so that you could perhaps craft a language that sounded more pleasant to you. Or maybe it could help you think about why certain sounds are pleasing to Anglophone ears and how that might differ in other languages or cultures.

Also this link, but it's incomplete. Some of the links on the reocities site seem broken:
