I was unable to find Gruvbox light theme, so I decided to create one myself.
The thing is still WIP and will be for a while but works for me atm.
Key components are color scheme and desktoptheme.
Over that I use simp1e gruvbox dark cursor, Tela light icons and Sonokai espresso Konsole theme (but I'm considering switch to gruvbox as well).
You can explore it on my GitLab
