@newsvan is also totally correct. The makita is deemed totally appropriate and vouched for by onefinity. Yes, a spindle is objectively “better”. In reality you gain some work time as there is nothing a spindle can do in this context a makita cannot also do, just maybe slower or with a few more passes.
A spindle is not a “must have”, but many cnc owners- especially the sort doing it as a hobby- are inveterate tinkerers. Look at all the fancy work tables on this site! A lot of it is totally for fun. Absolutely nothing wrong with that. But don’t lose sight of the reality that the machine was designed with the makita in mind and it is up to the task.
If you are looking to pick up some bits to get started with the makita i recommend the spetool bits on amazon. Inexpensive and fairly high quality. I use their 1/8 compression bit with a 3/4 inch cutting surface a lot! They sell good starter sets with endmills and vbits that will get you in the game cheaply.
