I've noticed that the CFW Starter Kit has a lot of extra files that are not mentioned in
https://3ds.hacks.guide/finalizing-setup, will these be deleted from the memory card after I finish setting up?
to me it seems easier to just follow
https://3ds.hacks.guide/finalizing-setup and only have these files on the memory card. Would that be OK?
There is GM9Megascript that deletes a handful of files when cleaning up the SD card. Other than that, no. Many of those files in that kit would need to be manually removed by user preference.
The cfw starter kit is for those who want the convenience of having most of the popular homebrew apps already collected for them, would like to explore stuff they're not familiar with, need a reference setup to figure out which files should go where, and debugging their 3DS systems for miscellaneous software issues.
Of course, the drawback is that the kit is considered excessive to those looking for a simple build where they already know a handful of homebrew titles that they specifically want.

My general reply to noobies with nonworking hacked 3DS systems assumes some of the following:
(1) They followed an unofficial guide such as YouTube video tutorials where their custom firmware setup is incomplete or critical procedures were skipped.
(2) The setup they're using has outdated arm9loaderhax custom firmware -or- really old versions of [ boot9strap / Luma3DS / GodMode9 ].
(3) Their efforts to revive their 3DS systems has comes up short, and they need a (nearly) sure proof way to get it back to bootable state.

I recommend you hardware test your empty SD card if you've never done so before. The safety of your data and saves will depend on verifying that the card you're using isn't fake or faulty.
You don't have to use the CFW starter kit or all of it. You can pull out only the files specified in the Finalizing Setup, or download them from their GitHub release source page.
Go ahead with Updating B9S if you're not sure or don't know if you're not using the latest boot9strap v1.3.
Do all of the Finalizing Setup. Too many people fail to follow through with the later sections.
So is it easier to copy everything from old console to new console or just do cfw fresh on new console
First, hack your second or replacement n3DSXL or n2DSXL system using 3ds.hacks.guide. See seedminer or ntrboot for the two most popular methods.
Second, once both your source and target systems have custom firmware, you decide whether you want to System Transfer your first system's NNID over to the second system using System Transfer.
-or-
You can copy or move just the
Nintendo 3DS folder with the SDTransfer method. (Ie, you wish to keep the NNID and user profile on the first system but want the 2nd system to have the same set of games as the 1st system).
