Absolutely not, installing a CA makes attacks which weren't previously possible now possible. A host firewall isn't doing anything a network provider (read: your ISP, coffee shop, vpn provider, etc) couldn't already do. At least you can possibly look at what the host firewall is doing.

Installing any third-party software that inspects network traffic makes attacks which weren't previously possible now possible, since that software can be targeted.

It depends on the host firewall... many quality operating systems allow host firewalls to apply process-based policy which your upstream certainly can’t achieve.
