* Skip the MX 2k/10k series – they don’t support SFP+ interfaces! (“No 10G WDM for you!”) Also no 1G, you need a separate step-down switch for that. I don’t know what SP Juniper thinks they’re targeting with these.
The 10k can take 10G SFP+ using an adapter. It works fine, but this can feel like a waste. Something like that: https://www.fs.com/fr/products/72582.html?attribute=2692&id=80750 This is seen as a 4x breakout cable.
* 1U/2U EX/QFX are reasonable edge devices as long as you’ve verified they can do what you need. Not core-router class IMHO.
QFX10k is different from the others. From my experience, it is very capable and the "Q" versions are quite versatile (many port configurations, cheap), but Juniper is trying to push the new PTXs with the same hardware, but not the same price tag, this is a bit confusing. I don't do MPLS, so I may not see its limitations, but it supports several full views and is the flagship for BGP EVPN VXLAN implementation for Juniper. -- The devil can cite Scripture for his purpose. -- William Shakespeare, "The Merchant of Venice"
