I'd like to have a list of English words sorted by popularity together with their pronunciations. I need it to learn the words I can't pronounce in popularity order. Is there anything like that I can find online?
Online, yes. Free, no. But you may be able to get in via your library or another institution. (In my case, I don't pay for my subscription; my college does.)
The OED is a historical dictionary, meaning that there's a lot of information about the etymology. It has a really nice Advanced Search, which lets you sort by frequency:
Frequency is based off eight "frequency bands", which may or may not be granular enough for your needs:
Each non-obsolete word is assigned to a frequency band based on its overall frequency score. Bands run from 8 (very high-frequency words) to 1 (very low-frequency). The scale is logarithmic: words in Band 8 are around ten times more frequent than words in Band 7, which in turn are around ten times more frequent than words in Band 6.
And as a dictionary, it does indeed have pronunciations in each non-obsolete entry (some have more than others):
It has many lists under https://www.vocabulary.com/lists/
American Heritage Dictionaries normally feature about 70,000 entries. From that multitude, the editors have chosen 100 words that are neither obscure nor outlandish that could give middle schoolers more aplomb and aptitude in their verbal encounters. If you're not sure whether that is something you need, study this list. Words selected by the Editors of the American Heritage® Dictionaries. Published by Houghton Mifflin Harcourt Publishing Company.
The top 1,000 vocabulary words have been carefully chosen to represent difficult but common words that appear in everyday academic and business writing. These words are also the most likely to appear on the SAT, ACT, GRE, and ToEFL. To create this list, we started with the words that give our users the most trouble and then ranked them by how frequently they appear in our corpus of billions of words from edited sources. If you only have time to study one list of words, this is the list.
I have picked one at random for illustration purposes:
