fresh (complete) install to an SSD+HDD equipped laptop

Can someone offer guidance so that I install fresh using my new SSD hardware?

I have Linux installed to my laptop HDD.
Code:prompt $ mylsblk

sda 931.5G
sda1 vfat 16G bios_grub
sda2 vfat /boot/efi 1G -EFI
sda3 ext4 /wrk 391.6G myWork
sda4 ext4 /home 100G myHome
sda5 swap [SWAP] 12G mySwap
sda6 ext4 /boot 1G myBoot
sda7 ext4 /var 30G myVar
sda8 ext4 / 80G myRoot
sda9 ext4 /vault 300G LnxVault VaultI've added a 256GB SSD to the workstation, made a partition table, and some partitions to prove that the install worked as expected. I plan to re-init the SSD during the fresh install.
Code:prompt $ mylsblk

sdb 238.5G
sdb1 vfat 512M SSD_EFI EFI Partition
sdb2 vfat 15.3G SSD_FAT32
sdb3 ext4 222.7G SSD_Ext4This SDD should easily accept a full install of my favorite distribution.
I have other questions about "frequent write" spaces such as /var/....
(I know to avoide swap and similar on SSD.)

I plan to continue use of /home and other "my data" spaces from the HDD.

Both drives have GUID Partition Tables (GPT)

CONFIGURATION:

• Linux Mint 19.3 w/ Cinnamon DE
• HDD only workstation

PROPOSED:

• Linux Mint 20.x w/ Cinnamon DE
• HDD + SSD workstation

Thanks in advance,
