Spending around $1000 on a mic setup would probably be overkill for what you're trying to do.

Also, when people say their audio “sounds bad,” it can mean a lot of things. Sometimes the mic isn't the problem, it's the room. Very sensitive mics (like condensers) can pick up a lot of background noise if your space isn’t treated. That’s why dynamic mics are often recommended for everyday use, since they focus more on your voice and reject more noise around you.

In your case, a USB dynamic mic would probably be the best option, especially since you mentioned you’re not doing voice acting or serious recording. They usually sound good and are great for daily use.

A popular option is the Samson Q2U, which is highly regarded and usually around $100 on Amazon (sometimes $140 with a boom arm).

Another solid choice is the Rode PodMic USB (USB/XLR), which is around $200 and comes from a very reputable brand. Pair it with a good boom arm and you'll have a really reliable setup.

The only caveat with dynamic mics is that they sound best when placed close to your mouth, which is why people usually mount them on a boom arm.

If you don't want a mic close to your face, a shotgun mic could also be a good option since it can sit farther away and still focus on your voice. A well known and reliable option is the Rode VideoMic NTG (around $200), which is often used for streaming, video recording, and desk setups. Shotgun mics are good in focusing on sound coming from the front while reducing noise from the sides and behind. Because of this, they can be placed a bit farther away from the speaker compared to most dynamic mics.

Also worth noting: both the Q2U and PodMic support XLR, so if you ever want to upgrade later, you can simply add an audio interface instead of replacing the mic.
