Read or listen to a lot of the kind of material you hope to be able to produce yourself (people speaking clearly and eloquently), or really just a lot of things in general—anything longform whether it’s essays or novels or non-fiction will help with vocabulary and style.
Feed it all into the maw of a woodchipper inside your head, to be chewed up and absorbed into your own habits of speech and thought. The more contact you have with lots of good examples, the more you can draw on the patterns and rhythms of it, to generate more like it.
But also practice. Lots of occasions of speaking, either in front of people or in quiet moments to yourself. Make a conscious effort to be clear, until it becomes more of an unconscious skill. At first that will mean thinking carefully to plan what you intend to say, so that you can deliver it with fluency and fluidity (honestly, not just “at first”—very probably that will always help). With time maybe you get sufficiently accustomed to make the thinking phase shorter and speak more ‘off the cuff’, but being able to speak unprepared in flawless prose is a genuinely rare skill and perhaps not a realistic target.
There are also classes and clubs you could try, either specifically for public speaking and speechmaking, or for performance more generally (like theatre/improv).
