Get it inspected before you start replacing stuff - seriously, don't guess on this one. Creaking and clunking can point to worn bushings, but they could also be sway bar links, struts starting to fail, or even something loose in the steering column. A shop can pinpoint what's actually worn in like 20 minutes, and then you'll know exactly what needs work instead of throwing money at parts that might be fine.
That said, bushings on a 2019 Civic are probably still decent shape mileage-wise - they're usually good for somewhere in the 80k-150k mile range depending on how rough your roads are and your driving style. If you're under 100k miles, they could just be starting to deteriorate, or it might genuinely be something else. I had a car once where I was convinced it was bushings making noise on turns, drove me nuts for weeks. Turned out the sway bar endlink was shot and was rattling around. Fixed that one component and it was silent. Total different issue, way cheaper to address.
The temperature thing matters too - if the noise gets way worse when it's cold out or first thing in the morning before the car warms up, that's classic bushing behavior. When rubber gets stiff and cold, it creaks. But if it's consistent regardless of temperature, you're probably looking at something that's actually broken or loose rather than just worn. Either way, get under there and have someone look before you decide on replacements.
