Your SPF policy is ~all. Because your DMARC policy is at enforcement, DMARC already acts on alignment failures regardless of the SPF qualifier, so this is informational. Tighten to -all once your sources are confirmed.
FIX
Once you are confident your SPF is correct, harden the policy to -all (hard fail).
MTA-STS protects against downgrade attacks during SMTP delivery. Recommended for serious senders.
FIX
Publish an MTA-STS policy at mta-sts.<your-domain> and a TXT record at _mta-sts.<your-domain>.
You meet DMARC requirements for BIMI but have no record. BIMI displays your logo in Gmail and other supporting clients.
FIX
Publish a BIMI record at default._bimi.<your-domain> pointing to your SVG logo. Add a VMC for full Gmail support.
