Feature description

• rejoin command to rejoin the match after leaving or disconnected by the server
• lobby remover when the game starts
• pos1 and pos2 coordinates accepted in the command or automatically detected: it is way easier especially with maps having no border blocks, admins need to build till the point
• team upgrades npc easier to find: you need a very long command to add the teamUpgrades npc, it would be faster to have it in /bw admin [arena] store add teamUpgrades

I feel like you want whole-world arenas, but I'm not entirely sure, because you mentioned border blocks. You do not need any border blocks? Pos1/pos2 is set to the location of the player executing the command, it does not matter if there is any block or not.

team upgrades npc easier to find: you need a very long command to add the teamUpgrades npc, it would be faster to have it in /bw admin [arena] store add teamUpgrades

TeamUpgrades NPC is a feature of SBA, not BedWars. It works by SBA supplying the custom shop file and using the BedWars command /bw admin <arena> store add <ShopkeeperName> <filename> <includeMainStore> to add the store. Until the upgrade shop is implemented in the main plugin, there is no reason to add a dedicated command for it.

Also please do not create a single issue for multiple feature requests.
