Alvar Aalto table solid wood: restore top  

Hi everyone, Willem from The Netherlands here. I've scoured this forum for tips/advice around restoring an old Alvar Aalto table I've purchased. I'm not an experienced wood worker, so coming here for advice before doing anything I'll regret.

The top has worn, scratches and one deeper scratch. My main question would be: how to best restore this? My guess would be it heavily depends on the table having a layer of veneer or being made out of solid wood with lacquer? Attached a few (up close) pictures. Thanks in advance!
