For cats, the AAFP (American Association of Feline Practitioners) maintains the go-to anatomical diagram. They recommend distal limb sites to make any injection-site sarcoma easier to manage: rabies in the right rear leg, FeLV in the left rear leg, FVRCP in the right front leg. This is the most widely referenced chart in clinics.
For dogs, WSAVA's vaccination guidelines are the standard. Their PDF guidelines document includes diagrams and site recommendations. Most SQ vaccines go over the shoulders, IM in the rear thigh muscle.
Two other useful hits. Revival Animal Health has a practical how-to page with site visuals aimed at shelter and rescue staff, which might be closest to what your team needs. ResearchGate also has a published diagram showing distal limb and tail injection sites for cats that you can download.
If you want something ready-made for team training, the AAFP feline vaccination site chart and the WSAVA dog guidelines PDF together cover both species without you having to draw anything. The Revival page is the most copy-and-paste friendly for a quick internal handout.
