Where are you compared to the $12,000 standard deduction? The biggest bang for your buck is making your deductions lumpy. If you aren't hitting your SALT cap, then you can basically pay your property taxes every other year for tax purposes (i.e., pay January1 and December 30 of 2020, then January 1, and December 30 of 2020) in most jurisdictions. So let's say you pay $5k in state income taxes and have $2,500 property taxes, and give about $2,500 a year. If you lump your property taxes and giving into alternate years (so assuming you didn't pay 2019 property taxes until 2020, that would mean paying your property tax before end of year, and you've given $2,500 so far this year, then you can go ahead and also "pre-give" for 2021 in December, then you basically get a $15k itemized deduction for 2020, and then a $12k standard deduction for 2021, rather than two $12k standard deductions. Not a ton of movement, but can net you an extra $1,100 tax savings every other year just by keeping enough cash on hand to pay your property taxes and do your giving early.
Just be glad you're single (for at least tax purposes). The $10k SALT deduction being the same for single filers or married filing jointly is a pretty stiff tax penalty on marriage. $2,400 a year not the biggest deal in the world, but annoying b/c it's so unreasonable.
ETA: If you have access to a 401k, be sure and max it our or put as much as possible into it. It's just about as good as it gets for non-business owners.
If you can max out the 401k and still have money left over, then do a roth or a non-deductible contribution to an IRA (so you can roll it into a roth later). No current deduction but basically just as good as the 401k deduction assuming you stay in the same tax bracket in retirement. And once you get it into a roth, that money is much easier to access than 401k money without penalty, so you might want to do that before even maxing out your 401k.
