Is there any good way to indicate you’re paraphrasing a quote without doing the specific thing of putting square brackets around every edit to show what you’ve changed?

I would do it where you paraphrase the quote as much as possible, have the beginning of the sentence reference the person you're paraphrasing, and where you leave the quote unchanged just put quotation marks directly around it.
Example
"The only thing we have to fear is fear itself"
becomes
As Roosevelt said in his inauguration speech, the "only thing" the United States had to fear was "fear itself."
Helps make it clear who youre citing, what parts are a quote, and what parts are you paraphrasing.
If this is for school or work check a style guide first they may have a different style for this but this is how I would do it personally.
What inspired this was trying to cut down quotes to fit in posts/titles with strict character limits so adding more words around it is actually the opposite of what I wanted to do.
