I would say that as you already know when you use a routing protocol on IPv6 the neighbor will always be the link local address from the interface from the neighbor itself,
So I would say why to use Dynamic( Cause it's easy,it's scalable as it's based on a unique value)
Why to use Static ( So you can create your own system to identify the neighbor, I have read that for security purposes you can use a mechanism that will create random EUI-64 based on a hash but as this is only for Link-Local address I would say it does not apply here)

Ideal world - use standard M-EUI-64 for link-local addresses and then use a FHRP like HSRP for the static address. That way your routers are all dynamic, but the address humans use for the default gateway can be something like fe80::VLAN#:1 or whatever makes sense for you. That said, I would try to stick with using RAs for your default gateway. The only exceptions should be infrastructure devices that either don't run or aren't configured with a routing protocol such as load balancers and firewalls.
Does anyone have or know of any Powershell scripts to collect information from Cisco switches (Nexus, layer 2) and output to csv or Excel? Need to document a number of Cisco switches with port, vlan, routes, ACL information. Thanks
