Oh I know I'm being unreasonable, and that my expectation is higher than I reasonably need.
I understand that just because my vault file might be accessed, that it doesn't mean my data is, and that accessing that is still a whole other ball game.
However, if I have a master vault with everything, I still feel more comfortable having absolute control over where it's stored and how it can be destroyed, and proprietary hosting doesn't do that for me. I also can't stand these subscription models popping up everywhere. I don't know if you're on a legacy 1password service, but they ONLY seem to offer a sub service at the moment. I just don't think it's value added enough to justify it, and it breaches my core requirements.
I had missed the keepass iOS compatible services, but you're right - it DOES look like what I want. I'm exploring a few clients now. So thanks!
Regarding last pass - i said they were reputable earlier. They've in fact had several breaches over the years. While technically not a wholesale breach, they are nevertheless enough of the kind of issues I'm concerned about:

2011 security incident
On Tuesday, May 3, 2011, LastPass discovered an anomaly in their incoming network traffic, then a similar anomaly in their outgoing traffic. Administrators found none of the hallmarks of a classic security breach (for example, a non-administrator user being elevated to administrator privileges), but neither could they determine the anomalies' cause. Furthermore, given the size of the anomalies, it was theoretically possible that data such as email addresses, the server salt, and the salted password hashes were copied from the LastPass database. To address the situation, LastPass took the "breached" servers offline so they could be rebuilt and, on May 4, 2011, requested all users change their master passwords. They said that while there was no direct evidence that any customer information was compromised, they preferred to err on the side of caution. However, the resulting user traffic overwhelmed the login servers, and company administrators—considering the possibility that existing passwords had been compromised was trivially small—asked users to delay changing their passwords until further notice.[27][28]
2015 security breach
On Monday, June 15, 2015, LastPass posted a blog post indicating that the LastPass team had discovered and halted suspicious activity on their network the previous Friday. Their investigation revealed that LastPass account email addresses, password reminders, server per user salts, and authentication hashes were compromised; however, encrypted user vault data had not been affected. The company blog said, "We are confident that our encryption measures are sufficient to protect the vast majority of users. LastPass strengthens the authentication hash with a random salt and 100,000 rounds of server-side PBKDF2-SHA256, in addition to the rounds performed client-side. This additional strengthening makes it difficult to attack the stolen hashes with any significant speed."[29][30]
2016 security incidents
In July 2016, a blog post published by independent online security firm Detectify detailed a method for reading plaintext passwords for arbitrary domains from a LastPass user's vault when that user visited a malicious web site. This vulnerability was made possible by poorly written URL parsing code in the LastPass extension. The flaw was not disclosed publicly by Detectify until LastPass was notified privately and able to fix their browser extension.[31] LastPass responded to the public disclosure by Detectify in a post on their own blog, in which they revealed knowledge of an additional vulnerability, discovered by a member of the Google Security Team, and already fixed by LastPass.[32]
2017 security incidents
On March 20, Tavis Ormandy discovered a vulnerability in the LastPass Chrome extension. The exploit applied to all LastPass clients, including Chrome, Firefox and Edge. These vulnerabilities were disabled on March 21, and patched on March 22.[33]
On March 25, Ormandy discovered an additional security flaw allowing remote code execution based on the user navigating to a malicious website. This vulnerability was also patched.[34][35]
2019 security incidents
On Friday, August 30, 2019, Tavis Ormandy reported a vulnerability in the LastPass browser extension in which Web sites with malicious JavaScript code could obtain a username and password inserted by the password manager on the previously visited site.[36][37] By September 13, 2019, Lastpass publicly announced the vulnerability, acknowledging the issue was limited to the Google Chrome and Opera extensions only; nonetheless, all platforms received the vulnerability patch.[38] [39]
