Bike Rack help asap

[BulliedBully]

I discovered my new hobby during this pandemic which is XC trail riding with my first MTB Trek Caliber 9. 

So right now I'm planning to buy and install my first ever bike rack to be attached on my Subie XV Crosstrek 2018. 

Here's the deal, I wanted to buy a Hitch-type bike rack that can handle 3 or more bikes cause my friends always ride me with (I don't ride solo for safety)

Of course roof-mount is not my option. I have prospected this item https://www.subaruonlineparts.com/sku/soa567b041.html but still half-hearted. Any thoughts?

Or any other recommendations? Lighweight, can handle 3 bikes, sturdy, durable, and easy to install bike rack.
