Wrong! The answer is 'no, www.watkins-home.com can not be forged',
since the spf record for watkins-home.com will be used when checking
spf on www.watkins-home.com. You are right of course that CNAME does
not mix with other records.

If the MAIL FROM is set to www.watkins-home.com, surely SPF will look
for a www.watkins-home.com TXT record. What will make it 'fall back'
to looking for the TXT record at watkins-home.com?

Because the CNAME is essentially a pointer to another domain name.  I'm set
up similarly (kitterman.com is an A record and www.kitterman.com is a
CNAME).  If you Dig the TXT record for www.kitterman.com, the TXT record for
kitterman.com is returned.

put that all in one line or
