I don’t have worries about password managers like bitwarden as the vault is zero knowledge and encrypted with a, to bitwarden, unknown key.

And I trust that bitwarden can secure their infrastructure better than me.

About your question what I host at home:
OPNsense
Veeam Backup and Replication (not (F)OSS but I like it and it’s reliable. We also use it at work so it helps my profession)
The *arr Suite
HortusFox (plant management)
Immich
Jellyfin
Syncthing
Resilio
Unifi Network Application (Also not FOSS)
Uptime Kuma
Wallos (subscription tracker. Pretty awesome overview!)
PiHole

Can’t remember when I started.
I believe it was around 2019 or 2020.
It started with a Raspberry because I wanted a NAS but was too cheap for a proper NAS appliance like a Synology NAS.
Fucked the install up a few times
Bricked the OS install during an upgrade (had 2 USB powered hard disks plugged in. But the PI had not enough to supply both and itself during writing to it so the network share sometimes failed)
Installed Plex
Found out Plex doesnt allow transcoding with the free version
Found out Jellyfin and installed it on the Pi.
Bad experience with Jellyfin and anime releases as they use ASS/SSA subtitles
Later upgraded to an i5-11th Gen NUC to get HWA transcoding on Jellyfin
Fucked up the Intel driver situation but HWA somehow worked
Inplace upgraded the NUC from Debian 10 to Debian 12 and restored my docker container from backup
(I assumed it would take like 4h or so to replace the SSD, install debian, install the core packages (like docker, etc.) and restore the files. In the end it took about 8h (after an 8h workday) and finished around 3am. But it worked. Very well on top.

The hobby is expensive but rewarding.
My stack:
HPE 1930-24G PoE switch
Unifi AP mini
HP ProDesk SFF with an i5-7th gen (manually upgraded to something we were throwing out. Harvested the CPU. Crosschecked the BIOS support with the quickspecs by HP) (Proxmox with OPNsense virtualized)
Intel i5-11th NUC (Docker host)
Intel i3-13th NUC (primary Proxmox host. Holds the Veeam Backup server)
Raspberry Pi 4 4GB (docker host with the sole purpose of doing pihole DNS)
uGreen DXP4800+ with 4x15TB in RAIDZ2 (swapped the OS with a TrueNAS Scale SSD.)

Newcomer:
GL-iNet Slate 7 as my travel router. Configured a Wireguard VPN on it with the OPNsense guide. Worked very well.
I have to commend the guide writer on it. But the steps were a bit confusing if you werent reading it carefully.
