ICOs implementations have varied, such that while your points about inverse value and transparency of fraction of offering may hold for some, ex. Bancor w/ it's "hidden ETH cap" announced at 80% full [1], it does not hold for many others, ex. SONM capping at 331,360,000 SNM for 117,337 ETH for a pre-determined max ~$42 million ICO [2]. Whether or not the SONM-style, Bancor-style, or some other style of ICO has "most frequently" been done is an open question?
