You're considering the Ryzen 5 5600G and Gigabyte B450 DS3H, and some recommend the B550 series. It's a bit confusing. Also, you're thinking about adding an RTX 2060 later.
The B450 DS3H is compatible with 5000 gen AMD CPUs according to Gigabytes' official page. However, HelpfulTechWizard notes that purchasing a B550 board would offer better features and a BIOS that supports these chips from the start.
Ryzen 6000 confirmed as AM5. Avoid purchasing AM4 for better long-term compatibility.
Not gaurenteed. A lot of boards either make new boards with old bioses (seen it here, boards manufactured over a month after release still shipping with old bioses), but there is a chance. on b450 its a beta bios (for everyone) that suports zen3, so its never offically suported
