If you have the data explorer plugin, there’s a pre-made report in there for ‘Inactive Users with no posts’. You could also tweak it a little to give you an interactive list where you can click through to their admin page:
SELECT
u.id AS user_id,
'/admin/users/' || u.id || '/' || u.username_lower AS admin_page_url,
u.created_at,
u.last_seen_at
FROM users u
WHERE u.active = false
ORDER BY u.id DESC
