Any suggestions for world map

Is there a possibility to have an offline/downloaded version of the worldmap?

Does that package need to have internet? Or can i somehow download a region the way google maps allows so i can use it without internet?

Any help is appreciated

If you set up your own local webserver then you can point worldmap at it...

but there is no automatic caching of tiles built in, so you would need to find your own source of tiles.
