Cloudways cdn

Do we need to use any cdn service with cloudways.
As it says it comes with Cloudwayscdn which is really fast. However i am not sure about it.
Also it says they have a buildin firewall does that mean i can eliminate cloudflare completely.
Do i need a pro plan of cloudwayscdn for 1$ a month? Will that be better?
Please suggest.
Traffic is from US AND UK
SERVER LOCATION IS US, VULTR
