migrating from CBS250 (access) CBS350 (core/distribution) -10G uplinks

[jason-g]

We are starting to plan around lifecycle upgrade/replacement of CBS350 in the core/distribution to a C1300 based switch (or pair of stacked 1300) based on the EOL notice
https://www.cisco.com/c/en/us/products/collateral/switches/business-350-series-managed-switches/business-350-series-switches-mod-eol.html
and likewise, our CBS250-24P-4G in the access layer (8 small closets each with a single CBS250-24P-4G) to C1200 series based on the EOL notice
https://www.cisco.com/c/en/us/products/collateral/switches/business-250-series-smart-switches/business-cbs250-series-switch-mod-eol.html

We currently only have 2x1G GigabitEthernet Port-Channel uplinks from each of the eight CB250 to the single CB3250
that uplink cabling is cat6a terminated to cat6a panels
looking to "Add value" and capacity as part of the lifecycle replacement/upgrade, and was thinking we could do 10G uplinks to our access switches using the SFP-10G-T-X
the C1300 series supports the SFP-10G-T-X (or just use C1300-24XT), but the C1200 series does not (has SFP+ slots on like C1200-24P-4X, but that particular SFP-10G-T-X is not on the supported list).
(the cabling runs are less than 30m for most access closets to distribution, so those that are over we could keep to 1G if needed)

So we would be stuck with 1G uplinks and I don't think there is appetite to pull SMF or MMF throughout this building to 8 closets.

is there any Cisco m-gig option or other recommendation to squeeze more bandwidth/capacity out of cat6a beyond 1G ?
this is a non-profit company, budget consensus, so looking for creative ways to add value out of what we have existing.
maybe there is another cisco product line we should consider. Prior to the CBS350/250 we had the SG200 (access) and SG500X (core/distribution) so that lower end "small business" tier/line has been the goto.   The licensing/support model needs to be simple, etc.

Appreciate any feedback.

   The maximum speed supported by a Cat6a cable is 10 Gbps (Gigabits per second). It can maintain this speed up to a distance of 100 meters (328 feet).

understood.  my issue is the SFP+ that I would like to use to take advantage of that cat6a is the  SFP-10G-T-X is NOT supported on C1200 series.   so if we choose to upgrade from cbs250 series to c1200 with -4X model (SFP+ uplinks) then we cannot use that optical transceiver.   not the end of the world, but would be nice to get a bandwidth increase with a lifecycle product replacement.   also the supported distance per the  SFP-10G-T-X is only 30m (for 10G ), not 100m  (100m if 100/1000 speeds)

  - My advise to go for a higher model ; C1200 is rather low end , just as cbs250 vs cbs350 ; check if you can use C1300
