How can I properly trim and scrub my SSD and filesystem?

I want to know how to properly trim my SSD and check for errors. My lsblk looks like this: 
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
zram0       252:0    0     4G  0 disk [SWAP]
nvme0n1     259:0    0   1.8T  0 disk 
├─nvme0n1p1 259:1    0   600M  0 part /boot/efi
├─nvme0n1p2 259:2    0     1G  0 part /boot
└─nvme0n1p3 259:3    0   1.8T  0 part /usr/share/wireplumber
                                      /usr/share/pipewire
                                      /usr/bin/sunshine-2024.629.13903.copr
                                      /var/home
                                      /var
                                      /sysroot/ostree/deploy/default/var
                                      /usr
                                      /etc
                                      /
                                      /sysroot

                                      /usr/bin/sunshine-2024.629.13903.copr
                                      /var/home
                                      /var
                                      /sysroot/ostree/deploy/default/var
                                      /usr
                                      /etc
                                      /
                                      /sysroot
Can I just use the following commands? 
# fstrim /
# btrfs scrub start /
# fstrim /
# btrfs scrub start /

automatic trimming is enabled by default systemctl status fstrim.timer so you should never have to think about that at least when it comes to any drive. for the btrfs part i dont have the commands on hand as im in bed and about to sleep 🙃
