Looking for opinions on a new Super fund

No it's not compulsory, but you are supposed to consider it. So if you don't want it just minute a reason why that is the case and job done.
FYI, reasoning in SMSF minutes can be anything - "Insurance for members was considered but rejected because all insurances are a scam run by the lizard people and controlled by the New World Order"

Can I buy a safe and crypto wallet with my SMSF?

 

Yes. Expenses in storing and protecting your SMSF assets are allowed.
Of course you wouldn't be allowed to store anything personal in it.
Again, you should minute your reasons behind this.

Vanguard plans to tackle locals in super
Vanguard, the US funds management giant that disrupted funds management and financial planning when it pioneered low cost index investing, is drawing up plans to manage the superannuation assets of Australians.

The firm also confirmed it plans to launch an upgraded version of its Personal Investor portal, which is understood to lay the foundations of a push into superannuation.
This is because it would create the digital portal to service both superannuation and non-superannuation portfolios.

"There’s more awareness in the value of our funds and so we thought it was the right time to bring an upgrade in the capability to serve individual investors, and to refresh the retail offer," Mr Kolimago said.

The new digital portal would allow individuals to set up a Vanguard account online and invest in around 40 Vanguard managed funds, its suite of listed exchange traded funds, and buy and sell shares on the S&P/ASX 300 Index.
Mr Kolimago said the redesign was informed by the US version of its product which had 50 million digital interactions with users.
The product would in theory allow investors to top up their non-superannuation investment portfolio at a lower cost than through an online brokerage account by allowing easy access to its managed fund offerings.

Vangard's asset-weighted expense ratio was just 0.09 percentage points at December 31, 2018, and other firms have been forced to respond by matching or undercutting the fund management giant.
That includes Fidelity, which launched a "Zero" index fund, which charges no fees.
