Could use some guidance - Enterprise Environment

Hey /r/networking!

I have recently taken over an environment that is has a mix of Lenovo ThinkSystem Switches and Arista Switches, which for me was completely out of the ordinary, but I found that they can do almost everything I am used to, just different CLI and naming conventions. Here is the current infrastructure:

2x NE1072T - These serve two main functions, they have 48x 10GbE ports and 6x QSFP ports, they connect to the firewall (fortigate 500E) and all client nodes

1x NE1032T (24x 10GbE and 8x SFP+) - This connects to ~8-10 lab machines, 2x SuperMicro Nearline Storage Arrays (10GbE only) and a few old 1GbE Servers

2x Arista 7050CX3 (32x QSSP) - These are two 100GbE Swiches with 32x QSFP ports. These serve as the backbone for our primary storage (10x nodes w/40GbE ports) each node has a port connected to each switch. It also utilized 40GbE to 10GbE Breakout cables to connect to our vCenter cluster (3x Lenovo SR630 Servers) as well as another data cluster (4x nodes) using 40GbE to 10GbE breakout cables.

I am thinking of getting 10GbE or 40GbE SFP+ cards for the two supermicro nearline storage arrays and connecting them direct to the arista switches. But I am still torn on how to properly configure the switch connections.

What I am seeking is the best HA configuration through a mixture of LACP Lag, vLAG(lenovo)/mLAG(Arista) to connect these switches together. Below is a screenshot of a quick and dirty Visio drawing.
