Most modern day households in developed countries use ISP owned routers

i recommend ubiquiti as a quality router that will last forever or a router that supports openwrt 

Exactly.... it really might be time to obtain and manage my own home router... For now I just firewall the crap out of each machine that has any importance.

Don't know about that. How can you make sure those smart tvs, roombas and playstations are not collecting tidbits of data like arp scans or even wireless SIDs and sending it as debug data? Heck... I'm pretty sure Windows and Google devices do that. 

I personally make sure to isolate always IOT crap into a separate VLAN. I also have pihole installed and the number of blocked random calls to sometrics.spyanalitics.io is astounding.

Your ISP is selling your sensitive network data to the highest bidder
