Without addressing the pros or cons of lesser-of-two-evils voting, I'd like to point out that if you vote in a solidly red or solidly blue state, your presidential vote might as well be for the best candidate – because your vote won't change how your state's electoral votes are allocated.
One place to check is https://www.realclearpolling.com/latest-polls/president/general-election. If your state isn't there, it probably means RCP reckons the winner of your state is a given – but by all means Google to verify.
EDIT: Or check https://projects.fivethirtyeight.com/polls/president-general/2024/ – state filter at the bottom of the page on mobile.
