How to set org-tag-alist on a per capture template?

Question

I would like to have different fast tag selections depending on the capture template used.

• Personal template - org-tag-alist = gym, family, friends, chores
• Work template - org-tag-alist = mettings, docs, seminar

I run the org-set-tags-command at the end but the selection doesn't show up. The functions are being called cause I can see the org-tag-alist changed in describe-variable.

It's prompting me for tags 0 Tags [add more using TAB] instead of the quick entry when I run org-set-tags-command. If I set org-tag-alist outside of the function it works but then I don't have different tags on a per template.

(defvar org-capture-templates nil)

(defun my/work-tags ()
  "Set work tags."
  (interactive)
  (setq org-tag-alist '(("meetings" . ?m) ("docs" . ?d) ("seminar" . ?s)))
 (= 1 2) ; Need to return string or nil.
  )

(defun my/personal-tags ()
  "Set personal tags."
  (interactive)
  (setq org-tag-alist '(("gym" . ?g) ("family" . ?f) ("friends" . ?F)("chores" . ?c)))
 (= 1 2) ; Need to return string or nil.
  )

(add-to-list 'org-capture-templates
                 '("W"          ; key
                   "Work"    ; name
                   entry        ; type
                   (file (lambda () (concat user-emacs-directory "todos.org" ))) ; target
                   "* %(my/work-tags) %^{Task}%^{DESCRIPTION}p" :prepend t))

(add-to-list 'org-capture-templates
                 '("P"          ; key
                   "Personal"    ; name
                   entry        ; type
                   (file (lambda () (concat user-emacs-directory "todos.org" ))) ; target
                   "* %(my/personal-tags) %^{Task}%^{DESCRIPTION}p" :prepend t))

I use vanilla emacs, but tried it on doom to make sure it wasn't my configuration.
