First of all, the term network congestion is the most fuzzy term in networking. Everyone know what happened on an event known as "congestion collapse". Everyone knows that host are supposed to do congestion control, to prevent congestion collapse from happening. Noone really knows/or agrees upon what the word congestion means.
Now, let's consider ...

This seems to assume that queues can have limited number of packets (true enough), but unlimited packet size (not true). The idea that a large message packet size uses fewer places in the queue is true, but it ignores reality that an interface can only serialize the packet bits at a certain speed (bandwidth), so that larger packets take proportionally longer ...

What I did until now is let's say create SVI for vlan 100 put ip on it - set vlan 100 as a native vlan on the trunk to reach the router untagged.
That is one valid way to do it.
But it doesn't work unfortunately...
Be sure your router has routes for each of your VLANs. The next hop should be SVI for Vlan 100.
If that doesn't work, please edit your ...

Problem is that I can reach routed port sourcing from both SVI's but no from the device being inside vlan 10
That indicates a problem with the VLAN trunk between switch and router. If you have no subinterface for VLAN 10 on the router, that VLAN ends on the trunk and tagged frames are dropped by the router.
You need to either
extend VLAN connectivity to ...

On Cisco devices, SVI's are configured just like a physical interface. They are named for the vlan they're attached to.
For example, the SVI for Vlan 10 is named interface vlan10. To assign an IPv4 address to it, you would type:
interface vlan10
ip address 192.0.2.1 255.255.255.0

An SVI is a Switched Virtual Interface. It is an interface for the VLAN itself on the switch. It can be a layer-3 interface (IP addressing) to allow the switch itself to participate in the VLAN.
A layer-2 switch can use a layer-3 SVI as its management interface, and it would also need a default gateway in the VLAN to allow the management interface to be ...
